I'm building my first AR-10 and I had no idea there were so many different qualities of steel and finishes for a BCG. Thank you for all the knowledge I just soaked up like a sponge, from your wisdom. 👍

[@ChrisUrsiny]

my favorite ar-15 bcg gotta be Geissele Automatics 5.56 Enhanced Bolt Carrier Group, yes it cost more however it runs smooth as silk, i have about 900 rounds on mine never cleaned it yet and it still runs great. 👍👍👍

[@JAM76ER]

I gotta watch this on my big tv later the phone isn’t cutting it! But what exciting video! I can’t wait to watch. Thanks Kota

[@zakmichael]

I've got a Lantac in my BCM rifle and it works as you would expect. It has some features for running suppressed that are beneficial. Never had an issue and it cleans up easily. I don't think you need to run a $250 BCG but it certainly doesn't hurt. The BCG is the heart of the rifle. If you were going to have 2 key items it would be the barrel and the BCG.

[@HannibalTX]

Don't forget the buffer. Proper functioning is a balance of all three to avoid smooth functioning without a recoil bounce. There are vids in here for the proper weighted buffer and there are about a dozen different buffers for full automatic, M16, AR15 and M4s. If you change bolt groups and go to a heavier barrel (or a longer one-20") you will need to address the buffer.

[@HannibalTX]

Sorry for the typo. I meant to say "Proper functioning is a balance of all three to ensure smooth functioning without a recoil bounce."

[@prongATO]

Exactly what I am struggling with while doing a new upper. Going to go BCM upper, MCMR handguard, Ballistic Advantage Premium 223 Wylde 14.5 barrel, et al. I have had great experiences with NP3 but not many people make them. Is the Guissele worth it? I’d really like a BCG that’s easy to clean. I am disabled and would rather spend more time shooting than cleaning.

[@shojus]

I bet you out of all of those BCG'S, they are manufactured by about 4-5 different companies...

[@JimYeats]

Probably. Nothing wrong with that. Just built to different specs and QC.

[@HTMLRu1ezD00d]

From what I read BCM buys from toolcraft. So you arent wrong.

[@michaelpawluk6791]

@@HTMLRu1ezD00d nope. They're manufacturerd by MicroBest, then sent to BCM to finish the fabrication, coating, and QC

[@michaelpawluk6791]

@Bill Bob no they don't. If BCM cannot source parts from their suppliers then they will be out of stock. It's happened before, and they're not the only company to do it. That's what good companies do. Sorry that you bought a toolcraft and told all your buddies it's the same as a BCM.

Good timing, i just got a FN bcg from sharkarms in the mail 20 min ago. F stamped carrier, mpf stamped bolt. Good stuff. Going away from the fancy coatings now and just stick to the tried and true

[@michaelpawluk6791]

I have that BCG from them too! I got it for my FN m16a4 upper. Look at the bolt, if the F is underlined it means it was manufactured by an FN subcontractor not actually FNMI. Pretty neat, at first I was like wtf, but I don't think FNMI actually makes bolts. The underlined F is only ever on the bolt, and it just means they approved of it and it went through the mandatory 45 round test for the military. Also I'm pretty sure those BCG's are from the M16A2 days, I bought a A2 stock kit from shark arms and the stock was an unissued M16A2 stock not the M16A4 (button on trapdoor has a bigger notch on M16A4). Also pretty neat

[@jaksahn3370]

[@thebrucechannel8061]

[@FreedomInc]

With properly staked gas key bolts,it really serves no real purpose. You domt hear about broken bcg's. The bolt is the part that needs to be solid and by far the HM defense HMB battle bolt is by far the best on the market. 4 years since it was first designed and they havent had not even one come back broken yet. Not even in military testing.

[@joesapienza8121]

@@FreedomInc ... That's your opinion. Having served 34 years as a United States Marine and having put tens of thousands of rounds through the M-16 / M-4 platforms , I've seen plenty of bolts fail. POF has a bolt with an excess of a million rounds of high pressure ammunition through it and it still chugs away like it's brand spanking new. Staked keys can still loosen , regardless of how well they were done. POF submitted their BCG to the military as well and it exceeded their endurance testing ten fold but was not adopted for one simple reason , price. Anyone knowing how military contracts work , should also know that while the part, weapon , ect. must meet certain criteria, price plays a very big part on purchasing as well. I'll stick with my POF any day of the week. Perfection doesn't come cheap.

[@richardjohnson4696]

I never thought I would have as many BCG's as I do. I am old school and I have three AR15 BCG's, two Colts and a Bushmaster, I have never had any issues with any of them. The new ones.. A BCM, Odin Works, Noveske(Rubber City), PSA in Nitride and Nickel Boron, Spikes, and BDU(White Industries). I really don't have a desire to spend a bunch of money on one. The Odin Works and Noveske in Nitride are super slick. The BCM and Spikes are phosphate, the BDU and PSA Nitride are slick, but nowhere near the Odin Works and Noveske. I just received the PSA nickel boron in their deal with 10 Pmags. That is going into my 300 upper build. I'd say the most I've spent on a BCG is $189 for the BCM, $180 for the Noveske during the peak of the covid/election parts scarcity. I don't think I have spent more than $120 for any of the rest, with the PSA and BDU being the cheapest being well under $100. The Odin Works was $99. I feel that if I have any issues with any of them, they would be taken care of by those reputable companies. Even the CMMG ones I have for their 22lr uppers and the CMMG 22lr retro fit kit for any AR 15. Watching the School of the American Rifle has been very useful in watching him do autopsies on different BCG's and testing their pass/fail with his go and no go gauges.

Shot peening is used on many fancy engine parts as well. It essentially hardens the outer layer of the steel, making it wear less. Although the coating on the bolt will still wear at the same rate whether shot peened or not

[@johnritchie4801]

No shot peening is not done to harden the outer surface, that is what processes such as Nitriding and case hardening are for. Shot peening induces a Compressive stress in the surface layer of the part which increases the fatigue resistance of the component. Fatigue cracks propagate as a result of a Tensile stress. Thus if the surface is in compression this compressive stress has to first be overcome by any applied tensile load before a Net tensile stress is realized in the component and this is why the fatigue resistance is improved.
