Bear Creek Arsenal M16 Cut 5.56 NATO Complete Bolt Carrier Group - Black Nitride

If you've read some of the negative reviews, you already know what to expect in terms of quality. The machining isn't perfect, there are some sharp/rough edges, and the quality of materials is lacking compared to more expensive counterparts. However....even at full price, this entire BCG is significantly cheaper than a bolt or carrier of some of those other brands. I spent about 20 minutes with a file and 220 grit sandpaper rounding out the sharp edges and knocking down a few rough spots. After that, the carrier slides freely and smoothly in my $30 Bear Creek upper receiver. While there were some initial issues, I really can't complain. The BCG is extremely inexpensive, and the work necessary to get it to perform as good as anything else was simple and quick. The rifle this went into has about 1200 rounds through it so far and this BCG has performed as flawlessly as my Adams Arms Piston hunting rifle and my AR9 with a JP BCG in it.

I have two BCA BCG's and they both have over 500 rounds (each) without a flaw.

Works great with my 300 blackout build. Would buy again.

Works Great, Just Clean First, Staking Is Fine, Fast Shipping !!

Was a little nervous taking a chance on this bcg since the price was so right for medium budget build. But it worked for me and works very well. Had a piss poor stake job, but that's nothing new, every bcg ive bought except my Lantac and fail zeros have had bad stake jobs. Its been around 10 months and a hand full of range trips, still works well without issues. If I remember correctly, when checking head space, it even had an upgraded extractor type kit in it (large donut) which is a plus in my book, because ive owned a couple bcg's that had extraction problems and had to buy the addidtional kit upgrades. For the price I got it for Id buy again and recommend to anyone. Took off one star for the really bad stake job.

Would have to agree with the staking is poorly done for the price on sale nothing I can't fix with some red lock tie a hammer and a metal chisel. Other than that one flaw looks and runs great. Note yes I could easily remove the staked bolts out of the gas key to put red lock tie on them reinstall and put a proper staking on them.

Just got it installed in the upper. Still waiting on a few parts for that, but so far so good.
The overall finish is nice and smooth and the stakes look good.
I will update this review if it turns out to be shite.

These are GREAT! And the low price is even better! Gas key was a little light on staking, but big deal, gabbed my auto/center punch and clicked in better staking.

After 10 shots the extractor shattered like glass. It’s made with cheap metal. Bear creek arsenal is junk. Don’t waste your money with them.

MPI BCA BCG are always a flawless work of maching, never a single issue, head space well. A great buy!
