Designed for those looking to save weight while still allowing for the use of a suppressor long-term, the BIG Gunner is ideal for suppressed shooters.

Behind the gas block will be a pseudo-Government profile tapering to a shoulder and 1.1" journal .625 gas block. In front of the gas block, the barrel will continue to taper to a 1/2x28 muzzle with full shoulder.

All for just about a single pound!
