Anderson Manufacturing Complete M16 / AR-15 Bolt Carrier Group - Salt Bath Nitride

Never disappointed with Anderson products. Great quality and reasonable price. High quality BCG.

Easy to Clean. I bought this BCG Earlier this year I build a light weight MSR for my wife we went with a BCM Upper LaRue Tactical PredatAR pencil barrel and gas block. I already have various Anderson Manufacturing Lowers and figured I'd try their BCG. I must say I was pleasantly surprised with the fit and finish of this Nitride BCG. All markings were as listed the treatment was even. The Bolt Carrier did have a "ghost swirl" under the treatment from machining on the flat portion below the Gas Key (where the charging handle would go) nothing worth complaining about but definitely wanted to mention on the review. It was in no way a "defect" or deal breaker. It's just a detail I noticed and I'm sure would not have been visible if the carrier was coated (i.e. NiB TiN Phosphate). I used FireClean to condition to BCG (I'm still a firm believer in the product) which resulted in smooth quiet cycling after a few passes with the charging handle. Went to the range went through 500 rounds first time and worked flawless with Tula Federal MagTech Wolf (brass) and Freedom Munition. took it home and cleaned up easily and quickly (I know it's not 10000 rounds but still) All in all I'm ordering another for Labor Day sale for my 3rd AR being built here in Kommiefornia. - #2A3P - #FaithFamilyFreedom

I installed this in my Aero upper it fit nicely although it took 2 cycles to get the 2nd round to fire After the 2nd try i pulled it out of the upper and removed a couple of small metal shavings and reassembled it it worked fine. I only got to fire 20 rnds so far but I've had no issues after the reassembly.

Everything is just fine except the staking. Whoever did this batch was lazy as hell!! They are staked but the rear one is very poorly done. Neither will turn I tested but I dont have a ton of confidence in the staking.

Stakes are little too shallow other than that a decent Anderson bcg 300 rounds in still works

Aside from the screws in the gas key being not much more than finger tight and fairly shallow stake which in the end was a good thing making tightening all that done easier. Purchase was last week of September 2016. Fit and finish otherwise was as expected.

Nice finish. Closed on Go Gauge on a couple different barrels.

Firing pin channel was not round, Anderson offered to take care of it but by the time I got the new bolt I had replaced with a BCM and stripped the Anderson one and sent their replacement back to them, won't take a chance on any more, their barrels are great though

Honestly I have built approximately two and a half Anderson rifles I sold one and a half but my question is do the Anderson Bolt carrier groups fire full Automatic or Semi Automatic because I am trying to use my rifle for hunting and in home defense without having Atf breathing down my neck or beating down my door just to arrest me for a hunting rifle

First one I ordered was perfect; Finish was great, function flawless. Ordered a second and noticed the finish was just dusty looking, not a smooth, shiny nitride like the first.
Tool markings all over the carrier. FTE was every 5 rounds or so, extractor eating lip off of brass and gouging the entire length of case. Noticed chatter marks on the bottom of the carrier after first test fire. Replaced with my original bolt and no issues.

Save your money and don't buy an Anderson bolt.
