Bear Creek Arsenal M16 Cut 5.56 NATO Complete Bolt Carrier Group - Black Nitride
Ratings & Reviews
At this price, who can complain?
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.
BCA BCG GIVES YOU BANG FOR YOUR BUCK
I have two BCA BCG's and they both have over 500 rounds (each) without a flaw.
Great BCG for the price

Works Just Fine

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.
So Far, So Good.

Just got it installed in the upper. Still waiting on a few parts for that, but so far so good.
<br>The overall finish is nice and smooth and the stakes look good.
<br>I will update this review if it turns out to be shite.
by Jon -
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.
by Matthew -
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 always a great product
by At the ready Armory -
MPI BCA BCG are always a flawless work of maching, never a single issue, head space well. A great buy!
'Okay'. Will work for spare. Will not buy again. Spend more, get more.

Finish on bolt itself is either super thin or improperly applied. Working the ejector pocket for 3 minutes has removed tge majority of any finish that ever existed there. Other bolts I own (Faxon, BCM, Brownells) have not had the finish literally rub off while function testing.
<br>Ejector pocket seems to have a burr or have a sharp edge on its unchamfered opening. I got hangups every ~8-10 'cycles' of my pressing spent brass into the bolt face to test ejector function.
<br>Machine work is acceptable. No sharp edges on mine. Faint swirl/machine marks are present in tight spots.
<br>Function while assembled is acceptable. Will fire this weekend and report back.
Best paper weight I own!

I purchased 2 of this BCG. Even on sale, it is over-priced. The metal work on both BCGs is course, and has several sharp and uneven edges. Working the CH, this BCG sounds like a cheese grater. That can't be good for the upper. Spend a little extra, and I suspect you will get a lot more quality. Unfortunately, 1 star is the lowest available rating that I can select. My advice: avoid this BCG!
Great bang for your buck!

Good looking basic nitride covered BCGs. The one I have tried worked just fine. There is no need to buy the more expensive mil-spec BCGs, in my opinion. There were staking marks where there should be on the gas key. The finish is nice quality. PA did a great job on delivery, and the price can't be beat.
Good BCG.every thing good but the key staked
by dave -
Haven't shot with it but jacking its smooth as greased BBs,No scratches or rubs inside the upper.Machined Finnish is very good.BUT! always a but,Right? to say the key is well staked is stretch.I wouldn't shoot it the way it came.
by Roger -
Smooth as silk, no machining marks, no overly sharp edges, bolt came oiled. Fits my ATI omi hybrid upper perfectly, no play or binding.
Ok for the money, make sure to head space these!
by Deadhorse -
Mine arrived super fast from PA as always, BCG had some pretty bad machining marks on the underside of the carrier, one of which is so bad it appeared to be a crack at first. Bolt spins on No-Go gauge on several brand name 556 chambered barrels, was faced a couple thousands to deep. PA customer service about the issue was awesome as always. As long as you inspect these and headspace them you shouldnt have any issues, overall a affordable BCG that works as designed.
Works well for lite use.

The BCG seems to operate as intended. However, the fit with the BCA upper and barrel seems to be a little off. A better quality control system, and final part finish, would make this a five star pick. It operates fine in the 300 Black out. But I had to use a polishing stone on some of the sharp edges. It is staked, properly. It just seems that BCA could go a little further with the quality control, to make this a perfect fit. "You get, what you pay for"!
Good Quality NITRIDE BCG
Turned my buddy on to these for a set of AR's he wanted me to build for him on a tight budget, and he ordered two..I assembled the rifles for him and both have functioned fine through about 500 rounds each..The finish is decent, plenty good for the price point..The staking looks a little less than ideal, but I think it's sufficiently done. C'mon folks, stop whining about no chrome! It's not advertised as chrome lined and salt nitride is an excellent treatment for carriers that will last. He used Anderson uppers and I didn't see any indication that these carriers were "digging in" to the upper as a previous reviewer mentioned..One of these had the issue with the retaining pin, but easily fixed...I highly recommend stripping them down and do a good cleaning and re-lube with a quality lube. I was so impressed with the quality for the price, that I'm fixing to order two for myself right now
Very good and affordable

Works great in my 300 blackout CBC upper. Lined up perfect no issues and shoots just fine. Can’t beat the price definitely recommend
Super Price on a Great Bolt
by David -
Got this bolt 12-21-17.....picked up in store...$59 Bucks!!! Super Deal... This is a great qualty part...functions smooth in my Anderson upper. Took a chance even with some of the bad reviews....because I also picked up one of thier side charging bolts a couple months ago and it worked perfect.
Only if you have a gas key stacking tool
by UT AR -
Have not had a chance to run a gun with the BCG. But so far quick inspect and I'm happy with it For it's price.
<br>Some of the edges are sharp enough to cut your finger. After a few rounds I'll have to check and see if it's cutting into my upper and file it down if needs be.
<br>As for staking. Yes it is staked... But in my opinion. And this is coming from a relative Noob. It is not staked properly. I plain on buying a staking tool. And making it better. But for the price I would buy again for a cheap build..
by Alexander -
Bought this for a low budget built. I was very impressed with the quality, nitride coated, came oiled, still took it apart and put oil on every thing. No problems, peared with a radical Arms upper from primary and a bcm ch, ran 120 rounds of 556 Brass and 20 rounds of tula steel case. No hiccups.
Really good discount BCG
by Shane -
Great discount BCG. Bought several at this point when Primary has them on sale at 60 bucks. Had to trade one back in. Seems they (BearCreek) had a bit of an issue in mid-2017 but they got it fixed and Primary was VERY helpful on the CS side of it to insure happy customers. I like to clean these and then literally soak/drown them down in oil for a moment (dripping) with a quick pat down to remove excess. Excellent performance with -0- glitches through 500 rds.<br><br>Btw....no chrome :)
$63 to my door... I ordered two!
by Steve Earl -
I can't find anything negative to say about it!
<br>I ran it in 2 different uppers and it performed flawlessly. I also like the "hex" looking cuts on the carrier sides. They make it stand out and give it a quality, robust look.
<br>These are top quality. The gas key is properly staked and the finish is nice. I ordered one to try it out, just ordered another and suggested to my buddy to do the same for his build.
Poor Quality Control
Gun would not cycle, the gas key was not installed correctly, the guide rails on the bolt were so sharp they were cutting into my upper receiver and had to polish them. Poor quality control.
