[b][/b][i][/i]Hello. My buddy has a 20" ar upper with an oversized bull barrel and wants another one but I have ni idea who makes these monsters. In front of the gas block it is straight 1.20" to the muzzle. The largest gas block I've ever known is .936 so would this be custom? If anyone knows where to get a barrel that size and a gas block, I'd appreciate the information. Thank you,
Jim D
