    Bought one of these barrels for a budget friendly 300 blk pistol build, overall quality is great, fit to upper was tight. Feed ramps look good, they look larger than the M4 but probably because its a 300 blk barrel… Overall very impressed. Have not gotten to the range yet to know accuracy.. but its a 10.5 barrel, we are not talking sub MOA anyways. 🙂
