AR battle zero deep dive- barrel length
HTML-код
- Опубликовано: 6 авг 2024
- How does the performance of your 5.56mm AR battle zero change with different barrel lengths? In this video we will shoot a 36yd zero side by side on cardboard out to 300 yards out of an 11.5" barrel and a 14.5" barrel. We will then take a close up look at where the rounds landed so that we can draw a conclusion around what to expect out for a battle zero out of your rifle.

It's like this man read every forum argument and said "Hold my beer"... Love it!
He really is reading my mind and I'm ok with it
Solving all the AR worlds arguments in a short series of videos. Can we get him to tackle world peace next? That should be a cake walk.
That’s 100% the vibe I’ve been getting with a bunch of his videos. One of the most underrated guys on here in my opinion. Loving all the real world data vs. theory with editing. Aloha 🤙🏽
PS: I come from big ranch Wyoming roots and loving his hat choices lately. 👍🏽
He did the same thing about a year ago and found the thirty six yard zero.. And found it was true out to 300.
I know! He's doing everything I've ever wondered and didn't have the resources to try myself. A true American hero.
I really hope you stick with this. You'll probably never have 3 mil subscribers because the masses demand goofy skits and shit getting blown up. However, there is a good sized group of us who appreciate informative and insightful content. Thanks for the hard work.
My plan is to keep pumping out content just like this…. I’m here to create content that’s entertaining for most viewers but provides some level of valuable takeaway in each video. Seems like most guntubers have moved more toward the entertaining side of things than data and value so I believe this is my niche. Really appreciate the support!
You deserve a million subscribers. The information he give is very well explained and laid out amazingly!! Thank you
he's a hidden gem
i totaly agree
Absolutely. One of the best long range shooting channels on the platform.
Excellent video as usual. Great information especially about the difference between 5.56 and .223. You are very well spoken and present your data clearly and concisely. Good job
You dont miss with the quality content. Keep it coming my man👍🏾
I’m only 4 minutes in…. I just want to say I really like the way you are laying out the intro to these videos. Your way of explaining and presenting the information you have for us, is being done in a manner that is simple, concise, and practical. It’s not only easily understood but lends itself to being used in the field for ourselves so that we may conserve valuable ammunition and waste less time figuring out things for ourselves! Keep up the good work my friend. And most of all , thanks!
The comparison did surprise me in contrasting the pressure distance between .223 and 5.56 ammo using overall distance between groups @300yds. Understandable, the 5.56 has more pressure, but for the group to be almost 4moa gap is bananas!!!! Great work and love the content!
Way back when I was in the army we used a 25/300 meter zero for M16A1s. So 300 meters was our point blank range where the bullet was supposed to stay within a 6" elevation change if I recall correctly. The maximum effective range for the rifle was supposed to be 460 meters, but you would have to guess your elevation hold at that distance since there was no way to dial it in for varying distances. A person that far away looks like they're less than half the width of your front sight post, which makes aiming hard enough already. A colonel once asked me if it a was characteristic of the M16 for bullet to rise like that. I guess he thought it defied gravity for the first 25 meters, until I told him the bullet starts to drop immediately upon exiting the barrel. I held my hands up at 2 different angles and told him, your line of sight is horizontal like this, but your barrel is actually pointed up like this. We had to treat some of our "superiors" like children, and couldn't use big words either. Even with this gentleman who was only one rank below a general (for any civilians who don't know).
Great videos, no nonsense or opinions, just facts. Interesting the difference in the 556 out of a shorter barrel. It would be interesting to see a similar study with different 300 BLK barrel lengths
This is the kind of data I’m looking for when I can’t get out to shoot thank you
Really surprised at the drop difference in both barrel length and 223 vs 556. Would like to see 13.7 vs 16 and 16 vs 18 to see if same difference in drop with 2” difference. Great content and I’m sure your channel will keep growing
I literally just purchased a 14.5” barrel chambered in 5.56. Thank you for your efforts! This is very helpful data. I’d love to see real world data battle zero’s in 16” as well if you haven’t already. Great channel brother! Keep it up!
Thanks so much for these videos! Love the deep dive and nuances of different components!
This is cool i really like my 11.5
I think the 11.5 is better them the mrk18 length because the velocity between the 2 is quite extreme.
Awesome data. Most important thing for everybody to remember is choose your zero and put rounds down range. Get familiar with what your rounds are doing at X distance. Correct your zero or correct your fundamentals.
My first 11.5 upper I zeroed 50/20. My newest is 36y
Coming from 20yrs of using AKs hold unders and slightly high at range is more comparable to the 36y zero. For me it’s muscle memory. Everything I grab points and shoots just about the same every time. Points and shoots for everybody else that has to use it just the same.
Thank you for confirming me never wanting to use 223 ammo. I didn't realize the difference would be that great but glad I've always picked up 5.56 loads. Once again amazing work and it's getting weird, kinda like you're reading my mind with these comparison.
I prefer the 100 yard zero with a 16" because all the holds are below the reticle
With other zeroes the POI is on, under, or over at different ranges
From 0-100 it's all height over bore, on at 100, then 100+ all about drop. Simple for my simple mind
Those are bigger drops than I had expected. This helps greatly with how best to optimize your training and how the ammo is going to change your performance. I’m going to eventually do the same with my 18”, 16” in 13.9” rifles to see the differences.
You should pull out the chrono and do a whole video on Maximum Point Blank Range and how it tweaks your battle zero.
A while back I ran the 'calculator' for MPBR and drop on a 12.5" It's not really a 36-300... more like a 34-2something. (I don't remember)
MPBR is your friend and ammo makes a pretty big difference, specially through a shorter barrel with regular rifle loads.
Having run MPBR over the years I have lost all my love for cartridge dedicated reticles. I'd love some decent red dots or LPVOs with MOA or MIL under the center dot instead of '5.56' drops.
Your videos are great. They should use these in high schools around the nation!
Awesome info bud. These battle zero videos are very useful and and always give interesting and actionable results. It was very interesting how the 14in was way more accurate than the 11in with the 223 ammo, but the groups for the 11in tightened up a lot when you switched to 5.56. Over the years I’ve migrated away from the short barrel 5.56’s though I used to love them. These days if I want to rock a short barrel I’ll go with 300 blackout, 277 wolverine, or sometimes even a 12.5 in 6.5 Grendel. The Grendel loses speed for sure with the short barrel but the 123gr pills still rock a target out to 600 yards or so.
I love what this channel is all about. My main rifles are 14.5 and 11.5. So this content is VERY instrumental in my thought process of how I run my rifles. I have a 36 yard zero on my home defense (10.5) rifle because I know if have to use it, it will be up close or less than 100 Yards. With your testing now I know to stay in my lane with short distances. LOL. Keep Up the good work.
Great work as usual, thank you.
Outstanding work again.
Great content. Thank you
Excellent!
Love the educational video bro. You helped me make my decision! 🙏🏽
Great job!!!
This series ate gold!!
Really underrated channel. Keep up the good work!!
Really excellent, thank you
Another excellent vid
Right on dude, great content!
I love all the detail!
wow this is great info. Thanks for doing the hard work.
Very informative, as usual. thanks Triple M.
Great info man!
Lots of value in this video, thanks for taking the time to get this data!
Muh favorite mountain man
Handy video with good data, thanks!
Great content. Thanks for sharing
Most informative piece of knowledge I had in a long time
Absolutely awesome technical walk through. Thank you
Looking forward to the next installments in the series. Great content! Clear, Concise, & Comprehensive!
I love your videos. They are so well put together and gives me real data
Sweet video man. Just goes to show how important it is to test your ammo and confirm your data.
Great info as usual!
Excellent video! Keep up the awesome work
Just phenomenal content, hands down some of the best on the internet. Very much appreciate the attention to detail and hard work to ensure everyone is understanding/considering all the subject matter covered.
Great video, very informative and enjoyable presentation, thank you!
Awesome break down of the data and what should be represented from both . Keep making valuable content .
Great vid!
Totally digging your channel. It let's me geek out on ballistics and satisfies the scientific method itch I get when trying to spend too much time choosing between good things. Keep up the great work.
Love this channel!
Love this content. Something most other guntubers don’t even come near to delivering.
This is great data collection that will help me in my data collection.
great info. interesting that the 556 11.5 had less drop than the 223 14.5 at 300 yds. The need for a high pressure fast burning powder optimized for shorter barrels is real. That's what the bi-metal sig 227 fury is all about come to think about it.
Great video. Great execution and display and explanation.
Great video.
Excellent
Good stuff. Clear lesson here is know your setup and your ballistics. The 36/300 zero as I learned it was specifically for our issued M4s with 14.5 inch barrels and 62gr M855, which will have a higher velocity than any 77gr OTM out of the same barrel. That being said, the 36/300 doesn’t apply to 77gr as you just proved, it’s more like a 36/225. Your demo shows exactly why any change in ammo or setup requires going back out to the range to verify your data.
I thought the 36/300 was originally for the 20” M16s but I could be mistaken
When I was in, we done a 25/200 I was thinking, with the A1 and later A2... I may be wrong. 1983
For what it is worth. The 36vyard zero is definitely for the 16 in mid length carbine, AND the 20 in AND the 14 point five. For real.
I read it on the internet, in this comment section. It has to be true. Oh dear, I'll hush.
Very good!
Thank you for all of your hard work you deserve a ton of credit! You are very easy to follow and I forward your videos to my newer shooting friends so they can catch up. Awesome Contant!
I asked for this 11.5 data and you delivered! I thank you, good sir!
Such good data and CLEAR explanations. Even going through the results in detail and the photo overlays are super helpful!! Keep up the great work and looking forward to this series. I’m kitting out this exact combo of an 11.5 BCM and 14.5 URGI with suppressors so this is really exciting stuff.
Awesome presentation man! Was a little worried in the beginning the test would get muddled up but you did a great job walking through the results! 💪🏻 One of my favorite channels for hard data analysis 👏🏻
Thank you.
Great video. I thought the 36 yard zero was based off of a 55 grain. Would like to see this 36 yard zero using 55 grain and 62 grain green tip.
Great test and very informative.
Thanks Brother.
Outstanding databasing. Ty for your testing regimen of real world data utilizing barrel lengths that so many citizens own. :-)
It is so nice to see someone with a 'Griffin Armament' !!
Man I love this channel!
Glad to hear you’re enjoying the content! Lots of fresh content on the works so hope you’ll stay tuned!
The 36/300 is for a 55 grain and 16" barrel with mid length gas system. The AR needs about 7 1/2" of barrel past the gas port .... according to Eugene Stoner to be reliable for function and dwell time. Sighting in with m855 62 gr at 36 yards then using the 77 gr. will skew your test a little. And you should chronograph each one to see the difference in velocity... which WILL have an affect on your group size and location. I've done these same tests since the 1980s. It's very informative.
I know this comment is about 3 months old but I believe what he was saying was he ran some 62gr to get it on paper and make sure it functioned correctly. Then he zeroed with the 77gr at 36yd before conducting the rest of the test.
@@brockmannwells I agree and that is what I understood it to be also but I stand by my statement. I use 77 gr. Razor Core from IMI. It shoots great but that doesn't change the fact that if you zero with one ammo you should use it exclusively. His results will be skewed because velocity can change impact location and it can get worse the further out you go.
Great video mate 👍
Good data, well communicated.
Interesting how much better that Griffin rifle grouped the 5.56 ammo, as well as the flatter trajectory.
My only improvement suggestion is to build yourself a decent sized target frame with some more area for bigger cardboard to de-clutter a bit.
Keep up the great work mate 👍
Most accurate and reliable shooting information I've ever seen on RUclips! For long distance shooting.....👍
Some misconceptions need to be cleared up: the 36/300 zero is what the USMC uses/used with 20" M16A4s w/62gr M855 (M855A1 might work too since it's supposed to be ballistically matched). That's the only barrel/load combination that will come close to 300 after the 36 yd preliminary zero. And the zero at 36 is just that, preliminary. The zero HAS TO BE CONFIRMED @ 300. The USMC Rifle Marksmanship manual specifically says that a rifle with only a 36 yd preliminary zero is absolutely not to be used for training or combat. It just just too close for slight POI errors to become apparent. This also applies to 50/200 zeros. You have to confirm it at 200
True, the short one is to get on paper at the other end. Not to bullseye out there.
i was a little confused about this video since his first video using the same rifle at 36 yard zero 300 yards it was basically zero. now using the same gun(14.5 inch babrrel) its all over the place at 300yards so what you said makes sense it must be a different ammunition that was being shot
Straight to the point. Very informative and good to watch. Love your content, do not ruin it during the growth of your channel ☝🏻🥳
For us science nerds best channel hands down
Great video
Love this.
I love my 14.5. I sold all my others and only run 14.5s now. But I don’t run suppressed so 🤷♂️.
Can you do a video on cheap 150 ball vs 168/175 smk and how different it is long range 308
@KevinMcGrath-777 I would have said military shit ammo if that’s what I meant. But ball ammo just means FMJs. I appreciate your insight though.
That mullet is epic❤
Thanks. That’s exactly the info I’ve been looking for.
Awesome! Really glad to hear you’re finding value in watching! Lots more content in the works so hope you’ll stay tuned!
Phenomenal video! This is something I’ve often speculated about but never cared to actually test it…nobody goes past the theoretical results in the “zero theory” videos. Occasionally you see them yes one rifle but NEVER see people talking about difference between different barrel lengths..love it
Another excellent video with the information we need. Demonstrating things helps people conceptualize what's actually happening, not on paper internet theory crafting.
Keep making videos bro. Love the content you do
Outstanding content, and so very clearly presented. You are a pro!
Thank you! Appreciate you taking the time to watch. 2 more videos coming in this series next weekend so hope you’ll stay tuned to check it out!
I'm amazed at how much difference in drop there was between .223 and 5.56 ammo. I would have guessed maybe 4-6 inches not 11+ inches.
oh so thats what it was, i saw part 1 of his zero video and it was dead center at 300yards and now its all over the place i couldn't figure out what changed i knew it was different ammunition but didn't know it was different caliber
Love your Videos!
3 Inches High at 100 Yards is an Outstanding Battle Zero.
Buddy, this is a absolutely absolutely wonderful idea. This series is exactly what people need to see. Thank you.
Really awesome to hear you find value in the content. The optic mount height compare video launches later this morning and then next Saturday and Sunday will be the bullet weight compare and the suppressed vs unsuppressed videos. Hope you’ll stay tuned and share with your buddies!
That’s very interesting, I would not have expected that much difference between .223 and 5.56!
Man you answer all my unanswered questions I think you have the easiest listening most informational channel around.
Really cool to hear you’re finding value in watching my content! Lots more just like this on the way so hope you’ll stay tuned!
Good stuff. Didn’t surprise much.
Great video. Very informative. I’d like to see this test with 55gr ammo.
Another great data point would be the difference in max point blank range for each barrel length for say, an 8" diameter target area.
For the valuable content you present to your audience on this platform I had to subscribe!
Love it! Really appreciate the support! Lots more content just like this in the works so hope you’ll stay tuned to check it out.
Nice presentation
Man that griffin’s lookin HOTTT 🥵 HIGHLY underrated rifles and cans
Agreed! Admittedly I wasn’t that aware of Griffin before they sent me the gear for use on the channel but now that I’ve got my hands on their stuff I’m very impressed. Really dig the lock up method of their dual lok cans and this mk2 rifle is slick. I’m thinking I’ll have dedicated review videos out later this year talking about my experience with each of their pieces of gear. Thanks for watching!
These videos are amazing.
Thanks!!
I’d really love to see you play with some PCCs as well.
Long range is my favorite, but I think a lot of us have more access to 100yard ranges.
You sir are a scholar and a gentleman
Thank you! Appreciate the support!
Awesome vid. Would love to see 16" 223 vs 5.56 at different grains/velocities.
