the 1/8 twist isnt milspec but it is the best twist imo 62 grain m855 shoots like a dream out of it and the stainless barrel made me coom in my pants
Absolutely the best AR Upper
My son a navy seal told me I could not get a better piece of equipment for the price. He was correct as usual
Have not used yet bolt on backorder
Excellent upper. Solid, accurate and reliable. Expected nothing less from BCM! Highly recommend anything built by BCM!
Excellent rifle
This is my third BCM upper and I have yet to be disappointed. Accurate and top notch fit and finish. Like the contrast of the stainless barrel. Thank you for making what is one of, if not the best upper for the money out there.
I've had this upper, paired with a BCM complete lower, BCM Mod 4B CH, BCM KAG forend grip, Armaspec Stealth Captured Spring in H2, and WMD NiB-X BCG for about 7 months now. It's had about 4k rounds through it, and has been flawless since day one.
The excellent build quality is apparent not only in lack of failures, but also the fit & finish, and handling/ergonomics/comfort. I can't speak more highly of the MCMR hand guard, especially when mated with a BCM KAG foregrip.
