It works now. Review by Marcus
This is the only Aero item that has not worked flawlessly for me, hence the 3 stars under value..
The bolt would not extract the round once it was in the chamber. Snapcaps ejected no problem but an actual live round would not. I tried three different brands of ammo, all with the same results.
As best I could figure was that there was a gap issue (I can't remember what the problem is actually called) with the bolt.
As I lacked the skill and tools to fix it, I took it to a gun smith to get checked out. He said it was what I thought it was and now the rifle works without issue.
It was cheaper to have the gun smith look at it than buy a new bolt.
Regardless I have and will continue to buy AP products. (Posted on 12/15/2017)

Excellently crafted! Review by Bryce
This is a great product for those on the market of bolts for the lr308 platform. This is very high quality and has a lot of serrations for the forward assist button. I would highly recommend this product. Thanks. (Posted on 12/14/2015)
Great Product! Review by AMHTactical LLC
I also purchased this BCG when it was on sale. QUALITY piece. I'm building an AR10 for the first time (i've built tons of AR15's, but never an AR10). I will be purchasing a lot more from Aero Precision! (Posted on 11/4/2015)
