Outstanding product! May 8, 2019
Reviewer: Jeff from Arlington, VA United States  
Great FDE color, gives my olderish BCM RECCE some pazzaz, not to mention that it’s A+ quality, nothing less than what I’ve come to expect from BCM. I’ve ran a few hundred rounds (all brass) through my rifle with this new BCG without issue. I suspect it’ll serve me well for countless more.

Smooth like butter May 8, 2019
Reviewer: GREGORY HAWKINS from ROCKFORD, IL United States  
I installed the BCM bolt carrier group into my upper, and it's so smooth and quiet. It slides like butter in my receiver. Ho hiccups, no hangups after taking it to the range, and throwing 500 rounds down range.  Clean up was a breeze.  Not much effort to get it looking like new again.
Great product.
