We are sick of over gassed civilian market gun companies. We wanted to make a barrel that would shoot your defense and duty ammo like a over gassed gun with 223 ammo. Our barrels use port holes of .071 giving you the perfect barrel for your next MK18 build. This pairs perfectly with our 9.6 MRS rail. This barrel will shoot most ammo on the market but won't shoot your super light loads. This is designed for the professional looking for a duty build.
