Lantac Enhanced M16 / AR-15 Bolt Carrier Group

Installed this bcg in an aero upper/lower with a Rosco 12.5 barrel ‘patrol’ length gas system. Using a Geissele super 42 braided spring and H2 buffer. Recoil felt surprisingly similar to a 16”/carbine gas system. 300 rounds unsuppressed through it flawlessly of 55gr 5.56 from PMCXtac, 5.56 55gr AAC, and some federal 223 55 gr softpoint hi-shok. Cleaned the entire bcg in 5 minutes or less. Well worth it for a 16” or under gun, especially if you get the sale prices.

I really love this BCG. When I originally received it I had a lot of issues with short stroking. I sent to Lantac and did some troubleshooting with them directly. We were able to diagnose the issue to most likely be some Permatex that got in the keyhole during the manufacturing process. They sent me a new one and I've put about 60 rounds through it so far with no issues (prior to that I couldn't do 1 without a short stroke).

Problems happen, but Lantac stood behind their product and worked with me on a solution. Can't ask for more than that.

Dont,hesitate to buy one .I'm glad I did fit and finish also quality definitely at another level .dam I was impressed very slick also testing has been flawless..

Simply the Best. Paired with an Odin adjustable gas block and upgraded spring. Not one jam, ftf, or misfeed in 1500 rnds.

First off, No other companies can beat PA prices. Secondly this is by far the nicest bcg on the market. The recoil impulse is lighter due to the enlarged gas ports and the super slick coating. It's paired with JP silent cap. system which makes my 6.5 grendel function smoother than I could have ever hoped. This BCG is definitely worth every penny, do yourself and your AR a favor a buy this for the both of yous-

This is a nice BCG and cleans up very easily. I bought it for my registered M16 with a carbine length Colt upper receiver and standard M4 buffer and spring. It will not work. FTF, short stroking in full auto. I tried various springs and buffer weights to no avail. Then I put the original Colt USGI carrier back in along with the original spring and buffer, and it ran perfect with M855 62 gr ammo. Maybe I can tweak it but I’m no skilled gunsmith. Just want a rifle that works.

I've ran this BCG for over eight months at the time of this review. Fit and finish is exemplary and really sets the standard for higher performing AR 15 style BCGs. The only issue I experienced was using it in a MK18 platform using M885 Green Tips. Being over-gassing and receiving consistent double feeds and failures to extract, I resolved this issue by simply replacing the extract spring assembly with a BCM extractor spring upgrade kit, issue resolved.

3,400 rds down the pipe and counting since last year when I ordered this from PA. Easy cleaning, top notch detail.

So with all the good reviews I went ahead and bought this for my new build. There was a lot of hype. This BCG was not at all what I thought. I was running a 18 inch 1/8 twist barrel with a .750 gas block. It has a geissele 42 buffer and spring. At first I was having cycling issues.i Thought is was my ammo. So I went from 223 PMC 55gr to hornady 75gr black match ammo. Still had problems. Then I Thought it was my geissele buffer and spring. Swapped them out with a new h1buffer and spring I had in my safe. Still had issues. Decided to use my BCM BCG, Rifle work flawlessly. Kept changing ammo types to make sure. So since I bought this damn thing decides to test it out. So to my finding, this bcg needs a lot of pressure to get it to cycle. The most I would take this would be a mid length gas systems with a 16 inch barrel. Hope this helps.
