The Fortis M2 Low-Profile Gas Block in stainless steel, sized for a .750-inch gas seat (brand part no. LPGB-SS-M2), is built to work cleanly with today’s match-grade barrels. Rather than pinning or set-screwing directly into the barrel in a way that can mar the finish, this low-profile gas block attaches with two set screws designed specifically for a .750 gas seat. It ships complete with a roll pin and the two set screws needed for installation, so there’s nothing extra to source.
