Not what I'd expect from Rainier ArmsReview by Kyle

I got this for my LR-308 build and despite the fact I had asked RA to headspace it with the barrel I bought, the bolt would not close on a GO gauge. the staking on the gas key was very suspect. So I sent it back with the barrel and they confirmed that it was indeed not headspaced and they sent me a new bolt. The bolt I received was new, but the carrier was the same one. They did not address the staking issue. The new bolt would close on a GO gauge but only with a lot of force on my part. I tried to close it on a new piece of Lapua brass and had the same issue - wayyyyyy toooo tight for a semi auto. I sent it back for a refund. (Posted on 10/4/2016)

Amazing Bolt Carrier Group! QPQ is very high end and this BCG is solid. Works well in my DPMS upper! I would definitely buy again. I read the other review and was hesitant at first to purchase but the product works well! (Posted on 8/15/2016)

Bought the this bcg with the Ultramatch barrel 18 inch rifle length. Call to get it headspaced but appears it didn't happen, received it and the parts don't match. Now, I have to wait two weeks for something I requested.
The quality of the bcg it's beautiful and it works on a Mega barrel. (Posted on 1/27/2016)
