Really like what you are doing with your channel!! Just went down the rabbit hole lol, it’s refreshing to see someone on YT actually point out short comings from popular manufacturers.
I've used this bcg for approximately 12k rounds and still love it. The face of the actual bolt finally started to flake off the coating in an area forward of the gas rings. But it doesn't seem to affect the function. I've noticed it's starting to go through gas rings a little faster than when new also. I like that the ejected cases always land at the four o'clock position. I just bought a new lantac bcg in the black nitride to replace this one, but I may keep using the old one till something fails. Overall I still think they make one hell of a bcg!
I have one of these and just fired 400 rounds through it. It's a great BCG, but yes like you said, the cam pin still marks up a little anyway which is no big deal. The Nickel boron finish seems to stain a bit too and become darker to no real detriment, but it does. Other than that I have no complaints. Casings eject nice and smooth/consistently and it continues to work even in a gun where the oil is cooked out of it. I also agree with the previous comment that they most definitely keep gas out of your face which is nice. I don't think it's a huge game changer or anything, but just a really nicely made BCG you can rely on and is great for a nicer rifle. I haven't had a single malfunction with this yet.
I appreciate the work you do. As someone whose building an AR this information is priceless. I do not like spending money on things that I will eventually have to replace due to poor quality. Keep it up man!
I know it's an old video but i like seeing your input on what is arguably my favorite BCG (run em in my 5.56 and my .308 rifles) i can ssy theyve run very well in my 12k plus rounds on both platforms. And its very possible it's a placebo thing but i can say i have less gass to the face when shooting my rifles with this BCG in it than my usual BCM of SOLGW BCG setups. Keep in putting out great and informative content, i love watching your stuff
I'm actually looking into purchasing one here soon, when I look it up online all I get is a bunch of people screeching that it's not worth the price and a bcm is just as good, but other than price complaining none of them seem to have any actual complaints, and to be honest I don't think they're overly expensive, do you have any opinions on that?
@@broderman5 I have the same Lantac bcg as in the video. It is very nice but I think functionally there is nothing outstanding about it. I shoot left handed so the gas being vented forward is a nice quality of life thing but honestly I am not that bothered shooting with regular bcgs. If you are committed to getting a Lantac then I would suggest getting the nitride version over the NiB. The NiB will begin to permanently discolor over time from fouling. It doesn't affect function but it is a cosmetic thing you should be aware of with NiB. But yeah, the BCM will also serve you just fine.
@@Deltaworks23 you sir are a gentleman and a scholar!!! That was probably the most respectful advice/comment I've ever received on RUclips, thank you for your response!
As a firearms enthusiast, and owner of multiple AR platform firearms, I find your videos both interesting 🤔 and instructive. I have been collecting various new AR parts over the years but have not actually built an AR. Assembled one yes. Your videos have reignited my interest in building firearms for my personal use. I would be interested is seeing how you conduct your off camera ejector checks. Also, is a complete pin set purchase advisable or should one just order the specific pin gauges used in your videos. I have ordered 223 and 556 gauges but would prefer those that don’t require ejector removal. Are yours purchased or made by hand? Thank you for all you do. You are making the world a better place by sharing your knowledge and expertise.
I bought what I think is a NIB BCG at a gun show about 4 years ago and it's made at a small shop in Ohio. I didn't really know anything about them then. I've been watching these videos so that I know what to look for. I've taken mine apart and examined everything very closely with a bore light and the machining looks very clean, including the inside parts that don't show. The staking is perfect as well. The screws are black and so is the extractor so I think that is a good sign. I wish I had all these gauges to measure that stuff. I think it's fine though because everything works fine. I did get lucky though because I had no idea what I was looking at when I bought it.
Chad in your opinion in all the years you've been doing this, who makes the best bcg and barrels, i want reliability, it would be a defence rifle Thank you so very much for your wonderful thorough in depth teaching, i so appreciate it Id love to learn to be a gunsmith, but dont have the money for your school, hence i appreciate all your videos Thank you Mark
I have this same bcg in an 11.5 suppressed SBR. I currently have about 8k round through it with no issues at all except the gas rings had to be replaced. Probably due to shooting full auto. Aside from that it's been a great BCG
It would have been nice to hear about the features that make the carrier special. As in the external o.d. which prevents the carrier from tilting, increasing accuracy, etc.
My nitrided enhanced Lantac BCG has done well for me. I put it in a 12.5" suppressed build and when changing out to mil spec bcg, I noticed a difference in gas in my general direction of my face. It still is quite gassy from the ejection port. I personally think Lantac BCGs are fine. They're way overpriced for what they are at $200. CMC makes an enhanced BCG with the same materials and roughly the same features minus the domed cam pin for the $140 price range.
great video. I put this exact Lantac NiB e-bcg in my first AR and it's been great after these first 1000+ rounds. What would be your pick for a quality premium BCG?
I have the black version of this one and it came with a short firing pin. Multiple light primer strikes. Swapped it with another pin and its been fine since.
@@aermotors did you ever get one of these? Been looking at one as an upgrade for my 12.5 in 300 Blk. My supperssor is about to come in and I've heard some really good things about this BCG for SBR or suppressed use. I looked at some of the adjustable bcg's but I'm just not sure about them. I do NOT have an adjustable gas block
@@mrpibb7781 I have 3 of the 5.56 and 2 of the .308. Have had problems with both .308 bolts locking up from carbon foul after only 50 rounds within the carrier. Cleaned them and they run smooth again, but I still need to shoot them again. 5.56 seem fine, don't have enough rounds through them yet to know, but I hope for the price I don't have issues.
@@aermotors Thanks for the update. a little disappointing considering the price. Not exactly an entry level bcg. With ammo prices the way they are I've been running steel cased 300 BO. Not the cleanest stuff in the world. LMT and JP are just TOO much for me. May end up trying the Bootleg ABCG a try
As far as barely passing on the efficiency, since so many ARs are overgassed this may not be such a bad thing on many of them. Slightly overgassed and barely passing on the efficiency seems like a pretty good combo for an AR that is reliable enough and pretty smooth shooting.
@@gordo5238 But yet most of them still go bang when you pull the trigger. Not everyone has money for expensive components that our machined to exacting standards.
Whis is magnetism bad? Is it just because of attracting unwanted debris? It would seem the strong shock of firing the weapon would de-magnetize anyway. Am i wrong? And thankyou!!
So I’ve been watching a lot of of physicals and have a question regarding the bore diameters when they’re in the yellows and you say not efficient. Wouldn’t that really depend on the dimensions of the bolt in relation to the bore?
What are u using to check the gas key? Looks like weed trimmer line? Can I just say this is a great channel! Would love to take some classes myself. Why the magnet check? How would it become magnetized and why would that be an issue...please and ty
What is the min/max measurement fafe to face for a AR10 308 bolt carrier, not including the bolt? I have one that is 7.86". I think its too long because my bolt catch doesn't lock the bolt back in the open position.
It is interesting (and this is no endorsement of any product, just a direct observation of two videos) but the more expensive Lantac had almost the exact same physical as the NiB Toolcraft bcg. Both into the yellow on gas efficiency, both had firing pins on the shorter side (the Toolcraft had some magnetism as well) but very similar.
Tail bore is likely slightly oversized for plating due to it being coated. Consideration Lantac needs to make when designing these because they do ask a hefty price.
Hey dude! Thanks for the awesome videos. I really appreciate the solid technical insight. Maybe we will bump into each other at Elk Neck sometime! -Much love!
He doesn't answer this questions anymore. He only tests a small sample size and every company has some degree of Monday products that pass QC. So some ppl who bought bcgs he said we're gtg, got bad samples and decided it's his fault and not the companys fault. So he stopped giving company recommendations. But if you watch some of his vids and google a little bit you will find the good bcgs. Hint it's the bcgs from the companys that sell quality stuff and have good QC.
I've heard him say several times that he has a soft spot for full chrome bolt. Also I've heard him talk about LMT proprietary springs for the extractor as well as lug balance. LMT shaves a lug opposite of the extractor. Seems like He's a LMT fan!
My POF bcg feels and sounds smoother than my other milspec bcg's. Im waiting on the conversion kits to come in to swap them over. Others would do it but POF has a patient on it.
Have you had any luck with steel cased ammo ? And if you do which brands would you use just in your opinion?? thank you and love the channel👍 stay safe🙏🇺🇸
yeah by the time you shoot five thousand rounds of steelcase the money that you saved verses shooting brass you could buy a barrel and have money left over.
Do you think lantac increased the bore diameter on purpose to compensate for the loss of gas due to the cuts they make closer to the bolt and increased weight at the tail?
I think this is a good question. Some may say, "duh, you obviously want the most gas efficiency possible"... but what if your upper if fitted with, say, an overgassed carbine-length barrel? Is it a bad thing for a little gas to escape through tiny gaps here and there due to those looser tolerances?
@@thegreatshitstain BINGO. Folks with properly ported middy or intermediate gas systems and/or adjustable gas blocks might be concerned in the freezing cold, in a filthy gun, with PMC Bronze. Maybe. Every normal person will be fine maybe even better off.
Don't think SOTAR is going to endorse a brand, might recommend testing existing BCG if you watch a few more videos the Nickel Boron finish can cause problems if not done properly. So in short it might be better to spend $ for a spec'd Nitrate finish then more money for coatings.
Solgw or sionics. Both have microbest bolts which are regarded as one of the best. Solgw actually warranties your bcg for life and will replace it even if you shoot it out
You probably watched all the vids by now, but he mentioned once in a video that he never saw a broken JP or LMT enhanced bolt lug. That may be a clue to his opinion....
I have a lantac bcg thats nitrided with 9310 bolt and their domed cam pin and this vs a psa premium with 8620 carpenter bolt bcg that I bought during the “Trump slump” when the qc was much higher then today imo. Given these 2 which would you run? The lantac is the M-Spec version.
I use all WMD BCG on my AR's... However I wish I would have done my homework better to buy LANTEC BCG.. Innovation and quality look superb.. GOOD VIDEO..!
Going to be honest, you should manufacture bcgs. I don't know if any one has ever told you but you would make a killing selling reliable good quality parts for ARs.
That's what they're specifically designed for. The "lower" tolerance for gas efficiency is there for all the crap being blown back while firing suppressed. If it were super tight it may cause an issue with so much back pressure. It's gotta have some room to breathe.
@@EarthAltar I think what you're saying totally makes sense. My question is, was this really an intentional design choice by Lantac, or just the chance result of using a cheaper/lower quality bolt inside their proprietary carrier?
@@thegreatshitstain I have two. One for .308, and one for .223. They are by no means "cheap". What I was referring to with the "enhanced" version (they also make a standard version) is that they are specifically designed to be used with a suppressor. They are ported differently than other BCG's to keep as much gas out of your face as possible. The lower tolerance on the bolt itself is probably by design for this system. Even without a suppressor they run like a bat out of hell. Believe me. I have zero complaints with either of mine.
@@EarthAltar I understand what you were referring to; hence, me writing that I agreed with your line of thinking. I have one as well (5.56/Nitride) that sees both suppressed and unsuppressed use. It's been fine... Of course for the price, it should be. But something that deserves being pointed out: the E-BCG really consists of an "enhanced" bolt carrier and cam pin design, but not an "enhanced" bolt. The carrier itself, with it's geometry and larger ports, does a great job of venting gas and keeping that gas moving towards the muzzle. The domed cam pin may or may not be anything special. I believe that the pin is optimized for use in Lantac's own upper receiver, which has slightly different geometry in the cam pin recess/raceway. But the bolt that comes in the group is not high-pressure tested (HPT) before magnetic particle inspection (MPI). I'm not saying the lack of HPT automatically means it's a crummy bolt; it may (and probably will) last thousands and thousands of rounds before failure. That being said, most "high end" AR manufacturers use bolts which have passed both HPT and MPI; and those bolts (at least from the few examples I've seen on SOTAR) seem to also have tighter tolerances. Not arguing for or against Lantac's design choices, just trying to play devil's advocate.
@@thegreatshitstain I hear ya, and often wondered myself about the testing. If SOTAR has taught us anything though it's that any part can fail, especially the bolt. All I can say is check headspace and look for improper wear. We're throwing these parts together from different manufacturers, and it's a miracle they function at all. Lol.
So my only question is after measuring the carrier they measured all yellow which is a pass but not great for gas seal. That being said isn't the exact measurement of the bolt in the carrier what will really determine the ability to seal? So what I am asking is if the bolt body is a little larger wouldn't that change the overall clearance & gas sealing? Love your videos, just asking because I'm getting ready to purchase my first AR-15.

What I was referring to with the "enhanced" version (they also make a standard version) is that they are specifically designed to be used with a suppressor. They are ported differently than other BCG's to keep as much gas out of your face as possible. The lower tolerance on the bolt itself is probably by design for this system. Even without a suppressor they run like a bat out of hell. Believe me. I have zero complaints with either of mine.
@@EarthAltar I understand what you were referring to; hence, me writing that I agreed with your line of thinking. I have one as well (5.56/Nitride) that sees both suppressed and unsuppressed use. It's been fine... Of course for the price, it should be.
But something that deserves being pointed out: the E-BCG really consists of an "enhanced" bolt carrier and cam pin design, but not an "enhanced" bolt. The carrier itself, with it's geometry and larger ports, does a great job of venting gas and keeping that gas moving towards the muzzle. The domed cam pin may or may not be anything special. I believe that the pin is optimized for use in Lantac's own upper receiver, which has slightly different geometry in the cam pin recess/raceway. But the bolt that comes in the group is not high-pressure tested (HPT) before magnetic particle inspection (MPI). I'm not saying the lack of HPT automatically means it's a crummy bolt; it may (and probably will) last thousands and thousands of rounds before failure. That being said, most "high end" AR manufacturers use bolts which have passed both HPT and MPI; and those bolts (at least from the few examples I've seen on SOTAR) seem to also have tighter tolerances.
Not arguing for or against Lantac's design choices, just trying to play devil's advocate.
@@thegreatshitstain I hear ya, and often wondered myself about the testing. If SOTAR has taught us anything though it's that any part can fail, especially the bolt. All I can say is check headspace and look for improper wear. We're throwing these parts together from different manufacturers, and it's a miracle they function at all. Lol.
Had a lantac enhanced BCG that wouldn't run at all in a mega machines 10.5 in upper
Gas inefficient for a bcg that's marketed and pushed as a suppressor BCG and includes an extra port for gas efficiency lol
Didn't measure the bolt shoulder
Have you ever tested a f1 bcg
Can I use this lantac ebcg to a gas piston ar15?
No.
Can u make a test also on the F1 durabolt and cryptic coatings bcg... trying to choose between those
2:39 is it just me or does the left hole not really look nicely deburred… sponsored product?
So my only question is after measuring the carrier they measured all yellow which is a pass but not great for gas seal. That being said isn't the exact measurement of the bolt in the carrier what will really determine the ability to seal? So what I am asking is if the bolt body is a little larger wouldn't that change the overall clearance & gas sealing? Love your videos, just asking because I'm getting ready to purchase my first AR-15.
