Anyone have an opinion on Columbia river barrels?
Am wanting a 18" middy in the bull profile, 936 gas block. Satarn made this barrel profile for Brownells but just recently dropped the bull profile, can only get the 875 gas block.
Columbia river can build this barrel but in a 1-18 twist rate, is this kinda of too fast for the bushmaster using bullets in 240-250 range?
Thanks...Eric
