Everything I've purchased over the past 2 wks - LMT 14.5 upper, Rainier BCG, etc, etc; a couple grand or so, has been outstanding! Entire purchase process and shipping / handling has been above excellence. In fact, getting ready right now to make another purchase! Thanks Rainier! (Posted on 9/15/2016)

Functioned great out of the box and was a perfect match for my Rainier build. The only thing left is a Rainier Charging Handle. (Posted on 8/27/2016)

Overall, a great carrier group. Looks good and runs even better! The machining inside the rear hollow area of the carrier could've been a tad nicer for having a near-$200 price tag, but it's hardly an issue; aesthetics only, to be quite honest. (Posted on 7/18/2016)
Very nice high quality BCGReview by Don

I am normally a BCG snob and mostly buy Youngs MFG chrome. This time I decided to try this one and I am very happy. It is very well made and the nickel boron feels very slick. The machine work is very nice and of course it cycles and runs great. Overall this is a very nice BCG for the money. (Posted on 6/4/2016)
