The key holing is brought up frequently in forum as the rifles being trash, and constantly stated that all Chinese gear is of low quality. I knew early on from some other channels it was due to rubber ammo being used. It’s silly to make assumptions and underestimate other militaries capabilities.
It's amusing how many people assumed that "China doesn't know how to make guns so all Chinese guns keyhole" after seeing a single instance of a QBZ191 keyholing. Out of all possible explanations for that instance of keyholing, that one definitely is at the bottom of the IQ scale. Seems like a coping strategy more than an actual explanation.
honestly I see one dude explained it is rubber bullet under a reddit and dude got downvoted af even got harassed, I assume some of them is just try avoid the fact that hurt their feeling rn lol
its not like there arent chinese guns in the us, hundreds of AKs and SKSs before the ban. You dont think they just kind of forgot how to make guns after 20 years?
I wish someone could get their hands on one of these guns and do a thorough live fire testing on different environmental conditions and an inside out video on how this gun works and how it compares the AK and AR platform.
@@gn4128 Exactly, that's why I'm waiting for someone to smuggle a real QBZ-191 to the States or even Canada and give their opinion on it, and not on some sort of civilian rifle or anything.
Some training facility does get their hands on them and does upload live fire video in China, the begining of this video should be a clip from them. They most certainly is not going to do a inside out video until the big name TV channel start releasing it. That could take years.
Going by the slow motion footage at 18:40 it seems to me that the movement of the bolt is very well balanced in that it does not impact in the rear. I wonder if this has been achieved by just tuning the gun very accurately to that specific ammo type and including an adjustable gas post for adverse environments or if the amount of bolt travel is more than in some other systems lacking this effect like military AR's.
I can't stop laugh seeing some dude refuse to believe the truth and shitpost "keyhole" around the internet and even see some dude explain it very likely a rubber bullet then get downvoted and harassed Before, I tend to assume it is arrogance leads to these people be overconfident to themselves. But seeing them rage and refuse to acknowledge their mistake when shown the truth. Most likely just cope and low IQ.
its ok, classic western racism, remember when the british lost Singapore and hongkong to the Japanese, the pilots were so fucking retarded that they thought the Japanese had small eyes so they couldn't see at night, and got obliterated. the more they underestimate the chinese the better for them in a real combat situation.
@@NeostormXLMAX maybe they did that video training(the one with the rubber keyholes) on purpose to create a hustle in the firearms community, it's not the first time china uses this type of content to make outsider underestimate them.
12:00 Adding mass to the buffer is not a perfect solution to the bolt/carrier mass ratio. The mass ratio is important for the energy retention of the carrier during bolt pickup, since it need to impart energy into the bolt to get it moving, but during bolt pickup, any kinetic energy imparted to the buffer cannot be used to move the bolt as it not rigidly connected to the carrier. Also as far as I understand the Garand-style helical rotation doesn't have enough rearward movement to give primary extraction but helps to reduce wear of the lugs and friction,
Honestly I don't have strong opinions either way. External pistons are simpler to clean and manufacture (outside of the AR platform), and work better w/ SBRs. Internal pistons have a better centre of gravity and generate less moments within the bolt carrier group. I kinda wonder why so few designs use the internal piston system. Maybe it was bc the tendency for the bolt carrier to heat up severely limits where you can place the charging handle? If we're just talking about the AR alone, then I feel like the in-line recoil system and cylindrically supported BCG just suits the internal piston better. It was designed like that from the beginning after all.
great video! the information and the presentation is a breath of fresh air in this community. Appreciate your dedication regards to explaining all the details of QBZ 191.
Awesome video I saw some pics on r/forgottenweapons of the rifle being disassembled and I noticed the bolt carrier which seemed just like an AR bolt carrier (but after seeing the other video, there are obvious and major differences) Also in the photos on the reddit post I didn't see any fcg pins so I assumed they used a pack, which they do now that I found this video. Super cool, and thank you
I honestly love the way you describe these underappreciated weapons, thank you so much. Also, do you plan on doing a video on the 191's predecessor, the QBZ-03?
You take as much time you need. Your analysis almost reminds me of C&Rsenal to an extent, and I know that takes a lot of time. Just do you, and we will wait patiently.👍
I'm more interested in the upper receiver materials, and the recoil spring. Plus, also the gas block portion and the barrels. It looks intuitive enough that the 191 got an exposed adjustable gas block. I guess it's titanium btw still not sure, if it's landed on PLA SF Units, it must be another version of premium build. I expect some upgrades on the barrel and the upper receiver, aftermarket trigger looks fairly interesting if it's available. The finish can be more beautiful and got to go through some cerayote to adapt with camo and mission need. However, the stock looks a little bit off, if there's attachment point for sling etc it would be great.

Hmm I'm thinking of making a video on the QSZ193 rn, since I found a bunch of patent documents. The QSZ92 is interesting too, and I planned to buy a civ version but when Trudeau announced the handgun freeze in Canada they flew off the shelves, haven't seen one since... I also have some firearm design ideas that I want to tinker around with. Gosh I wish I lived in a place where it's legal to make your own guns and test it in the woods...
@@cabbage6015 Depending on what you do, it is and isn't legal in the US to make your own guns and test them in the woods, but it's definitely better. We have the Norinco sanctions, however, if the gun has been in private hands for 5 years it can legally come into the US as the law is written. Nobody has ever done this to a QBZ-97, but I'm seriously considering it. There are sources other than Canada too, such as Italy. I don't know the 3d printer laws in Canada, but if you make sure to steer clear of making legally prosecutable things with it you can do a lot of prototyping. I'm friends with a Brazilian guy prototyping an entire CAD-designed assault rifle with unique gas system, trigger pack, receivers, cartridge, everything. It's genuinely awesome to see a plastic version of what was only digital exist in real life, in somebody's hands.
@@cabbage6015 o.o That's awesome man! Only thing I'll say, is that to minimize the size and weight of your overall weapon, minimize the size and mass of your bolt and how it locks into the barrel. Especially the bolt specifically, because like a snowball rolling downhill it drives the mass of the entire action. Really excited to see what you come up with.
@@superfamilyallosauridae6505 oh it’s a handgun tho (but everything you said applies). That’s also why it has the potential to be legally finicky since handguns are so tightly restricted in Canada. I’ve also had an idea to make a 3d printed semi auto .17 hmr using an off the shelf barrel, but I emailed the RCMP and they told me I need to send them complete technical drawings for approval, which is kind of a pain. I wanted to do it just by trial and error, but idk what would happen if the initial design I send them end up not working. Worst case scenario I have to send a set of drawings every time I make a modification to the design…
Watched your first qbz-191 video and subscribed instantly. Simply love your analysis and eye for details. I really wonder why the Chinese ditched qbz 95 and what benefits does this new conventional design bring. They could've used 95's working mechanism and designed it into a conventional weapon from its current bullpup guise. I ask this as i haven't heard anyone complaining about 95's reliability. What objectives did they achieve with this new weapon design?
Glad you enjoyed! I think they switch to this design partly to provide more attachment mounting surfaces. Their patent documents also said AK-style bolt carrier groups are more bulky and heavy, so they used the AR-style this time to reduce weight. I also think that the 95's trigger mechanism is a bit bulky, especially with the linear hammer.
Are there any other obscure eastern rifles that we might see a video on? Singapore is a little talked about military mecha in SEA and their illustrious domestic defense contractor Singapore Technologies is known for producing world class defense technologies in a multitude of domains. Their small arms branch ST Kinetics is responsible for their new service rifle, the BR18. Which remains virtually unknown in western circles.
Konstantin Konev is a russian, that have an English dubbed video that explains about re-engagements and many other topics. He also have a channel in russian (more content) but you can use audio translation.
Really great video, I learned a lot from this series. Btw I know QBZ191 does have a version for export. I am looking forward to a video of Cabbage shooting QBZ191!😁
Hello , great video. I have a question , you said that ar15 doesnt have helical lugs and that ak does which helps with primary extraction. But i have also seen many people in forums say that ar15 also has primary extraction and that when bolt is rotated a bit the cartridge also longitudinally moves slightly. Maybe ar15 has very tiny helix angle so that from picture you showed it looked like it was flat but in reality maybe it has some tiny helix angle? Or does it achieve primary extraction through some other ways?
@@cabbage6015 thank you for answer, i guess its just the good old forum myth. Because i just now scrolled down a bit on the forums and other people also disagreed with them and said that ar15 doesnt have primary extraction. However they also said this "The AR does not have this primary extraction. The AR bolt does have reliefs on the left rear corners of the lugs that allow diagonal movement, but they don't force it." Do you know anything about those "reliefs" that this guy is talking about? It sounded interesting to me and my first time hearing it
@@thomasschumacher5318 I believe they’re talking about the chamfers at the edges of the locking lugs, but I think those are just to relieve sharp edges, they have no significant effect on extraction
Great video as always. I do have a request/suggestion that it would be very helpful if you could upload an abridged version(10-15min) of all the three qbz 191 videos, which could be used as a single point reference .
Third time watching this video... I don't think QBU191 is a IAR like M27 since PLA has also switched to their new SAW and GPMG. It has a full auto function just because PLA likes aggressive firepower.
Agressive firepower? I've mostly see 'em going towards a more flexible side, but I'm not a gun/military expert I'm just here to know more about norinco really.
@parko-nib China basically inherit this style from Soviet army and their idea is simply bigger gun is better. And they are actually good at designing lightweight weapons with strong firepower.
@@calciumoxide3385 i mean if you know what you're doing bigger gun does equal better, also lets chat a bit(i want to help cabbage's algorithm reach) Where exactly did that come from? Most of the military gear i see the pla use is more tactical and cost effective as possible, the only one that I'VE seen fit your category a bit is the QLU-11(and it's more like a over-engineered deadly multi tool than anything really)
@@calciumoxide3385 well no, i can, but i don't really find their big guns following the soviet logic(bigger = better), btw I'm here to learn more about norinco, 1 week ago i didn't even know they existed, any info is welcomed.
Yep, they just hate the "SoCiAliSt dIcTaToRsHiP"(tho they never even thought of reading marx much less engels and lenin) and will ignore solid facts in order to throw hate at china, i mean this doesn't change shit to me, norinco stuff are top tier and I'm gonna keep buying it one way or another.
interesting to see how the chinese military (at least part of it, or their "NOT A PMC BRO PLEASE BELIEVE ME BRO") have transitioned towards (for lack of a better term) "operator" kit. Like, you see how they are running drills in this video. it might be for the camera, but usually I have only seen that with western militaries.
I'm sure you've noticed a lot people point out the lack of a folding stock in this weapon. I personally don't find it necessary but it'd be cool to have one. Now just for arguments sake, is it possible for them to somehow integrate a folding stock into the current configuration? Or will it have to undergo major redesigns...What are your thoughts?
Hmm in terms of engineering I think they’ll have to do something like the LAW folder since the recoil spring is in the receiver extension like on an AR. I don’t think they will be able to fit a recoil mechanism on top of the bolt carrier like the MCX, due to the high ejection angle, and they also have cam lug locking mechanism up there. Whether they feel the need to field a folding stock variant? I have no idea 😕
I wonder, is QBZ-191 bolt carrier and buffer tube separate entities or are they connected? If someone wants to customize the buffer tube in the future, will it be as easy as taking out the old one and dropping in the new one?
Excellent work man, Really liking your in depth analysis and the work you put into the CAD. I too spent more time modelling a Glock slide in ProE than doing my university assignments 🤔🥴😅👌 I'll enjoy that special cookie now😜
I'm kinda hesitant to do it since most of the information I could find is from this guy's video: ruclips.net/video/5inorXoBhXQ/видео.html I feel like if I do it, 70% of my video would be clips from his video...
@@cabbage6015 I see, thanks for the link! Personally I wouldn't mind if you do it. I think you've found a niche in Chinese weapons Also wouldn't mind if you could deep dive on the Chinese pistols that you've done on your IG, the quiz was fun and educational!
Hi there, I tried looking up the video source for [9], but it appears to have been deleted. Do you know the context of it, like who was demonstrating the rifle and in what capacity? Thanks
It’s the clip shown at 3:40. I believe they’re just checking the zero of their optics. I included that clip bc it is uncut from the shooting to showing the target, to prove that the gun wasn’t keyholing
@@cabbage6015 So these guys would be actual PLA soldiers in the clip correct? Especially since I understand firearm ownership would be heavily restricted in China
@@cabbage6015 Interesting, because the guy closest to the camera appears to be wearing a pair of FCS/FMA AMPs, a clone of the Ops Core AMP. Notice the wiring in-between the ear cups goes behind the headband, a dead giveaway that it's the FCS/FMA version. Tbf, using them myself they're actually pretty damn good, interesting to see these guys went out of their way to get them lmao.
It's a great video. What do you think the gap in the upper left corner of the ejection port is for? I know it's the bolt carrier because it hits the upper receiver pinduring recoil
If I remember correctly, the ejection port on prototype guns are much smaller from top to bottom. It seems like that caused ejection issues so they had to enlarge the top of the ejection port
@@cabbage6015 Yes, the bullet case is thrown diagonally upwards, rather than directly from the side like AR. What I am thinking is whether this small gap in the mud test will cause the firearm to malfunction.
I made 3 videos on the QBZ191. This video is the third one. You probably missed the 2nd video, where I corrected a few mistakes in the 1st, and that includes the trigger pack. I’d recommend that you watch the 2nd video, bc the first one has a lot of misinformation
Have you entertained starting a blog? Sort of like forgotten weapons? I think it's going to be easier for people who like long-form explanations that just don't make the cut for a long, extended video 🤔🤔 Also, if you have some short videos, I think you can put them on RUclips as well. I sure don't mind interesting short videos 👍👍
Yeah I have thought about starting a blog. The character limit for Instagram posts are just too restrictive for some of my more detailed contents. I'll have to look more into it though
They are actually using, some of them directly use the trademark of holosun, while others actually use the domestic trademark "昊阳". Some force orders use the internal force serial number.
Thanks for another great video about the QBZ191 family. This rifle has some defects, but people who know the concept behind this design could accept that. To be more precise, the safe-auto-semi selector, the polymer handguard etc. But critics should know QBZ 191 is designed for large scale army, all those gentlemen who have to carry the rifle from average elevation exceeding 4,500 metres to extreme temperatures have ranged from −52.3 °C to 39.3 °C. Polymer furniture is the best solution for these environments, just like the AK12 family choose to have polymer furniture. The auto-preferred selector is the habit-based design from the original type 56 to type 95. This design inertia might be the only thing 191 should have changed. In real battles, safety should be always on until the soldier pulls the trigger. Safe to semi should be a subconscious move, and semi to auto could be a conscious decision even when making contact with the enemy. The QBZ 191 family would be better if there are Chinese versions of SOCOM M4A1 SBRs and RECCEs. Change the selector to safe-semi-auto, design a better and stronger freefloat handguard for different lengths and shorten the suppressor.
absolutely keep believing it, also yes all Chinese tanks are also made out of cardboard. and their ships too don't worry about it. you will win with your eyes cloased

Hmm I'm thinking of making a video on the QSZ193 rn, since I found a bunch of patent documents. The QSZ92 is interesting too, and I planned to buy a civ version but when Trudeau announced the handgun freeze in Canada they flew off the shelves, haven't seen one since... I also have some firearm design ideas that I want to tinker around with. Gosh I wish I lived in a place where it's legal to make your own guns and test it in the woods...
@@cabbage6015 Depending on what you do, it is and isn't legal in the US to make your own guns and test them in the woods, but it's definitely better.
We have the Norinco sanctions, however, if the gun has been in private hands for 5 years it can legally come into the US as the law is written. Nobody has ever done this to a QBZ-97, but I'm seriously considering it. There are sources other than Canada too, such as Italy.
I don't know the 3d printer laws in Canada, but if you make sure to steer clear of making legally prosecutable things with it you can do a lot of prototyping. I'm friends with a Brazilian guy prototyping an entire CAD-designed assault rifle with unique gas system, trigger pack, receivers, cartridge, everything.
It's genuinely awesome to see a plastic version of what was only digital exist in real life, in somebody's hands.
@@superfamilyallosauridae6505 Yeah I'll by drafting up my design in CAD in the near future. Will call the RCMP to ask about 3D printing regulation
@@cabbage6015 o.o
That's awesome man! Only thing I'll say, is that to minimize the size and weight of your overall weapon, minimize the size and mass of your bolt and how it locks into the barrel. Especially the bolt specifically, because like a snowball rolling downhill it drives the mass of the entire action.
Really excited to see what you come up with.
@@superfamilyallosauridae6505 oh it’s a handgun tho (but everything you said applies). That’s also why it has the potential to be legally finicky since handguns are so tightly restricted in Canada. I’ve also had an idea to make a 3d printed semi auto .17 hmr using an off the shelf barrel, but I emailed the RCMP and they told me I need to send them complete technical drawings for approval, which is kind of a pain. I wanted to do it just by trial and error, but idk what would happen if the initial design I send them end up not working. Worst case scenario I have to send a set of drawings every time I make a modification to the design…
thanks for the cookie, cabbage
Watched your first qbz-191 video and subscribed instantly. Simply love your analysis and eye for details. I really wonder why the Chinese ditched qbz 95 and what benefits does this new conventional design bring. They could've used 95's working mechanism and designed it into a conventional weapon from its current bullpup guise. I ask this as i haven't heard anyone complaining about 95's reliability. What objectives did they achieve with this new weapon design?
Glad you enjoyed! I think they switch to this design partly to provide more attachment mounting surfaces. Their patent documents also said AK-style bolt carrier groups are more bulky and heavy, so they used the AR-style this time to reduce weight. I also think that the 95's trigger mechanism is a bit bulky, especially with the linear hammer.
95的设计是为了配合当时的机械化部队改革，部队装备了大量的战车等等载具。无托设计由于枪的整体长度较短，同时保留枪管长度，所以是一个天然的优势。劣势也非常明显，拓展性太差，很难加装瞄具。
现在弹药技术进步到可以让短枪管打出高初速，那么就不需要长枪管了，无托布局就没有存在的必要了，回归有托布局不影响使用的同时还不影响拓展性。所以191就出现了
这系列视频是我见过对QBZ191结构原理剖析最详细的视频了
Are there any other obscure eastern rifles that we might see a video on? Singapore is a little talked about military mecha in SEA and their illustrious domestic defense contractor Singapore Technologies is known for producing world class defense technologies in a multitude of domains. Their small arms branch ST Kinetics is responsible for their new service rifle, the BR18. Which remains virtually unknown in western circles.
Hmm that one is interesting, I’ve never heard of it before. It depends on how much info I can find tho
@@cabbage6015 they speak English and Chinese there, so it’s entirely possible you may be able to find English patent documents
Konstantin Konev is a russian, that have an English dubbed video that explains about re-engagements and many other topics.
He also have a channel in russian (more content) but you can use audio translation.
Thanks for the recommendation. He’s a great source of knowledge
You're amazing man
Please, make a video about the Imbel's IA2 rifle.
Really great video, I learned a lot from this series. Btw I know QBZ191 does have a version for export. I am looking forward to a video of Cabbage shooting QBZ191!😁
Hello , great video. I have a question , you said that ar15 doesnt have helical lugs and that ak does which helps with primary extraction. But i have also seen many people in forums say that ar15 also has primary extraction and that when bolt is rotated a bit the cartridge also longitudinally moves slightly. Maybe ar15 has very tiny helix angle so that from picture you showed it looked like it was flat but in reality maybe it has some tiny helix angle? Or does it achieve primary extraction through some other ways?
I have never heard of primary extraction being achieved on an AR-15, by helical locking lugs or any other means 🙁
@@cabbage6015 thank you for answer, i guess its just the good old forum myth. Because i just now scrolled down a bit on the forums and other people also disagreed with them and said that ar15 doesnt have primary extraction. However they also said this "The AR does not have this primary extraction.
The AR bolt does have reliefs on the left rear corners of the lugs that allow diagonal movement, but they don't force it." Do you know anything about those "reliefs" that this guy is talking about? It sounded interesting to me and my first time hearing it
@@thomasschumacher5318 I believe they’re talking about the chamfers at the edges of the locking lugs, but I think those are just to relieve sharp edges, they have no significant effect on extraction
@@cabbage6015 i see, thank you so much :)
I respect your willingness to update on this topic
Great video as always. I do have a request/suggestion that it would be very helpful if you could upload an abridged version(10-15min) of all the three qbz 191 videos, which could be used as a single point reference .
Great job I love this video
Third time watching this video...
I don't think QBU191 is a IAR like M27 since PLA has also switched to their new SAW and GPMG. It has a full auto function just because PLA likes aggressive firepower.
Agressive firepower? I've mostly see 'em going towards a more flexible side, but I'm not a gun/military expert I'm just here to know more about norinco really.
@parko-nib China basically inherit this style from Soviet army and their idea is simply bigger gun is better. And they are actually good at designing lightweight weapons with strong firepower.
@@calciumoxide3385 i mean if you know what you're doing bigger gun does equal better, also lets chat a bit(i want to help cabbage's algorithm reach)
Where exactly did that come from? Most of the military gear i see the pla use is more tactical and cost effective as possible, the only one that I'VE seen fit your category a bit is the QLU-11(and it's more like a over-engineered deadly multi tool than anything really)
@@parko-nib I actually don't understand what your question is. You mean you can't find any big guns that PLA use?
@@calciumoxide3385 well no, i can, but i don't really find their big guns following the soviet logic(bigger = better), btw I'm here to learn more about norinco, 1 week ago i didn't even know they existed, any info is welcomed.
People claiming the 191 is garbage don't understand how guns and military training work.
Yep, they just hate the "SoCiAliSt dIcTaToRsHiP"(tho they never even thought of reading marx much less engels and lenin) and will ignore solid facts in order to throw hate at china, i mean this doesn't change shit to me, norinco stuff are top tier and I'm gonna keep buying it one way or another.
interesting to see how the chinese military (at least part of it, or their "NOT A PMC BRO PLEASE BELIEVE ME BRO") have transitioned towards (for lack of a better term) "operator" kit. Like, you see how they are running drills in this video. it might be for the camera, but usually I have only seen that with western militaries.
I'm sure you've noticed a lot people point out the lack of a folding stock in this weapon. I personally don't find it necessary but it'd be cool to have one.
Now just for arguments sake, is it possible for them to somehow integrate a folding stock into the current configuration? Or will it have to undergo major redesigns...What are your thoughts?
Hmm in terms of engineering I think they’ll have to do something like the LAW folder since the recoil spring is in the receiver extension like on an AR. I don’t think they will be able to fit a recoil mechanism on top of the bolt carrier like the MCX, due to the high ejection angle, and they also have cam lug locking mechanism up there.
Whether they feel the need to field a folding stock variant? I have no idea 😕
PLA still fields a large amount of type 95 in their arsenal, so I dont think a folding stock is too much of a concern for them
cabbage = gunfucious
I wonder, is QBZ-191 bolt carrier and buffer tube separate entities or are they connected? If someone wants to customize the buffer tube in the future, will it be as easy as taking out the old one and dropping in the new one?
What 3-D application are you using?
I used Solidworks for the trigger pack, but recently my SW license expired and I switched to Fusion 360
Excellent work man,
Really liking your in depth analysis and the work you put into the CAD.
I too spent more time modelling a Glock slide in ProE than doing my university assignments 🤔🥴😅👌
I'll enjoy that special cookie now😜
Will you be doing QCQ 171 / CS LS 7 ?
I'm kinda hesitant to do it since most of the information I could find is from this guy's video: ruclips.net/video/5inorXoBhXQ/видео.html
I feel like if I do it, 70% of my video would be clips from his video...
@@cabbage6015 I see, thanks for the link! Personally I wouldn't mind if you do it. I think you've found a niche in Chinese weapons
Also wouldn't mind if you could deep dive on the Chinese pistols that you've done on your IG, the quiz was fun and educational!
Hi there, I tried looking up the video source for [9], but it appears to have been deleted. Do you know the context of it, like who was demonstrating the rifle and in what capacity? Thanks
It’s the clip shown at 3:40. I believe they’re just checking the zero of their optics. I included that clip bc it is uncut from the shooting to showing the target, to prove that the gun wasn’t keyholing
@@cabbage6015 So these guys would be actual PLA soldiers in the clip correct? Especially since I understand firearm ownership would be heavily restricted in China
@@han6211 I think they’re SWAT, but yeah, a government entity
@@cabbage6015 Interesting, because the guy closest to the camera appears to be wearing a pair of FCS/FMA AMPs, a clone of the Ops Core AMP. Notice the wiring in-between the ear cups goes behind the headband, a dead giveaway that it's the FCS/FMA version. Tbf, using them myself they're actually pretty damn good, interesting to see these guys went out of their way to get them lmao.
It's a great video. What do you think the gap in the upper left corner of the ejection port is for? I know it's the bolt carrier because it hits the upper receiver pinduring recoil
If I remember correctly, the ejection port on prototype guns are much smaller from top to bottom. It seems like that caused ejection issues so they had to enlarge the top of the ejection port
@@cabbage6015 Yes, the bullet case is thrown diagonally upwards, rather than directly from the side like AR. What I am thinking is whether this small gap in the mud test will cause the firearm to malfunction.
@@cabbage6015What is the muzzle velocity of the DBP 191?
What modeling software do you use? Is that a SolidWorks assembly?
I initially modelled the assembly in Solidworks, then animated it in Fusion360 bc my SW license ran out
I'm currently learning SW, but it's good to know Fusion and Mastercam are just as good.@@cabbage6015
@cabbage Correct me if I am wrong but I thought you said in a previous video that the trigger pack is based on the ar, not the ak?
I made 3 videos on the QBZ191. This video is the third one. You probably missed the 2nd video, where I corrected a few mistakes in the 1st, and that includes the trigger pack. I’d recommend that you watch the 2nd video, bc the first one has a lot of misinformation
@@cabbage6015 thanks for the clarification
Nice video
Have you entertained starting a blog? Sort of like forgotten weapons? I think it's going to be easier for people who like long-form explanations that just don't make the cut for a long, extended video 🤔🤔
Also, if you have some short videos, I think you can put them on RUclips as well. I sure don't mind interesting short videos 👍👍
Yeah I have thought about starting a blog. The character limit for Instagram posts are just too restrictive for some of my more detailed contents. I'll have to look more into it though
Nice 👍🏻
干货，up主辛苦了，subscribed👍
He don't understand Chinese mate , he vietnamese 😃
Why dont the chinese use holosun? They use aimpoint in the vid
I don't think the ones in the vid are Aimpoint. They're Huoyoung, which as far as I can tell share OEM with Holosun
They are actually using, some of them directly use the trademark of holosun, while others actually use the domestic trademark "昊阳". Some force orders use the internal force serial number.
Thanks for another great video about the QBZ191 family.
This rifle has some defects, but people who know the concept behind this design could accept that. To be more precise, the safe-auto-semi selector, the polymer handguard etc. But critics should know QBZ 191 is designed for large scale army, all those gentlemen who have to carry the rifle from average elevation exceeding 4,500 metres to extreme temperatures have ranged from −52.3 °C to 39.3 °C. Polymer furniture is the best solution for these environments, just like the AK12 family choose to have polymer furniture.
The auto-preferred selector is the habit-based design from the original type 56 to type 95. This design inertia might be the only thing 191 should have changed. In real battles, safety should be always on until the soldier pulls the trigger. Safe to semi should be a subconscious move, and semi to auto could be a conscious decision even when making contact with the enemy.
The QBZ 191 family would be better if there are Chinese versions of SOCOM M4A1 SBRs and RECCEs. Change the selector to safe-semi-auto, design a better and stronger freefloat handguard for different lengths and shorten the suppressor.
There they are if you scroll down to variants.
The Chinese really watched too many Trex Arms videos.

absolutely keep believing it,
also yes all Chinese tanks are also made out of cardboard.

@@NeostormXLMAXyou misspelled the closed mate(just adding comments to increase cabbage's algorithm reach)
I don't understand guns, what is your final conclusion, is it a good gun? Still garbage.
