Anderson Manufacturing Complete M16 Cut AR-15 Bolt Carrier Group - Parkerized

Great fast service. PA is my go to for parts, from now on. I bought this Bolt for my new 300 Blackout build I just finished. Can’t wait to get after some coyotes now!

I have put about 2100 rounds through my gun since putting in this BCG. This was for my range gun so I went with a cheaper option. This functions better than my Brownells and PSA standard Nitride BCG's (Could be the parkerized coating or the pairing with Anderson's Upper). After 100 rounds it is super smooth. Just make sure to get some rounds through the barrel to break in the BCG and you will not be disappointed. Not one light primer strike or misfire. Used with standard carbine-length gas tube (Aero) and a 16 inch barrel(Anderson). Used a 3oz buffer and enhanced buffer spring (Expo). I have used Tula steel ammo with this flawlessly. Probably about 800 of the rounds were steel and about 1300 brass rounds. I have used different types of ammo from 55 grain to 77 grain. Not one failure to eject. I clean it after every time I go to the range. I just wipe off everything I can see with G96 and a rag. Have yet to take apart and clean the "insides" of it. Hope this helps.

I've built probably a couple of hundred AR platform firearms using these bolts. Best bang for the buck on the market. I have never had an issue with one. Oil it, and run it. I run one in my full auto, no issues. Anderson makes quality parts.

I have a problem getting my rifle to cycle with this BCG. Since the day I got it, i have to force the BCG into the forward position after every 50 rounds or so.

I believe this firing pin is too short, two rounds may fire correctly then the third the firing pin just puts a mark on the primer not enough to set it off. Looking at the BCG, the firing barely comes out of its hole. I have ordered a new firing pin a Fail Safe brand pin. May have to break down and buy a new BCG

I bought this bcg the last time it was on sale.The bolt looked fine when I first looked at it, I slipped it into my upper and it would not go in all the way.Upon further inspection I found the gas key to be defective.The part of the gas key that slides onto the gas tube was flat on the bottom,not allowing the two,to come together properly.I really don’t know how this got by the QC process but it did.I just bought a gas key and fixed it myself rather than going thru the return process.The rest of the Bcg looks ok but I haven’t put any rounds thru it yet.

I had to take it apart and oil it once i did no problems!

I ordered it Wednesday, it shipped an hour after I ordered and was here the next day despite only paying ground shipping. That SHIPS FAST claim is no joke. The BCG is overall a good value for the money.
<br>Pros: Milspec, MPI, inexpensive but not cheaply made
<br>cons: A little sticky out of the box
<br>overall I recommend but it's a good idea to clean it with hoppes and clp before taking it out to shoot

I tried this in 2 different uppers would not fire in either took it apart and the channel for the firing pin in it is not round looks almost heart shaped,emailed Anderson waiting on response this is not a primary arms issue, I like the lowers and barrels but nothing else

I ordered this product about a month ago for a build that I was putting together. When I received it I simply put it with the other pile of parts waiting to be assembled. Tonight I meant to put it all together and was a bit disappointed.
<br>Metallic flakes covered the surface of the bolt, that seemed unusual. Looking closer, the ejector pin is protruding from the side of the bolt, which is usually recessed into the hole a bit. The finish on the locking lugs also appear to be worn. It almost appears if the bolt has been used.
<br>In contrast to the bolt, the bolt carrier itself seems to be in fine condition.
<br>Seems like I got a bad one. I will be replacing the bolt before shooting my new build, the one that came with this carrier group seems untrustworthy.

Everything is good except the tribe staking job on the gas key. The stakes are no where near the gas key bolts. 3 stars because I have to re-stake it. Otherwise seems like a high quality bcg.

nice product works flawlessly

I purchased this for one of my AR builds. Fit and finish seemed good until firing. BCG would not extract the fired round from the camber. Tried different loads different brass...etc. I ended up getting the extractor rebuild kit from BCM. Now the BCG works great but I should not have had to rebuild it this soon in the game.

I have been looking at this bolt carrier But can someone tell me how it work's. I am not getting my upper for about eight weeks so I have time to look around.

I bought 2 of these and once everything got a touch of grease on the bearing spots it worked great for 3 sessions now approx 5000 rounds

Part shipped quickly, and fit into the Anderson receiver group perfectly. Haven't fired the weapon yet, but I'm certain it'll be just fine. The fit and finish was as it was should be.

Used with Anderson Upper, for the money you can't beat this combo.

Trying to wrap up a few builds and these were on sale at the right time. Excellent quality, fast service... always satisfied with Primary Arms !!!

I have used several Anderson parts and lowers with zero complaints. And as for Primary Arms service and shipping, They are the best in the business.

Just as good as my other one that I paid more for.

Items always as described, fast shipping, great prices, and unbeatable customer service when you need help!Jerry Garcia sets the bar for great customer service!

Great quality bolt carrier group. Magnetic particle inspected as well.

Quick shippingFunctions fine Very happy with the transaction

as advertised.works fine

Got this with an Anderson upper and both works flawlessly will definitely buy again when I build another
