Rugged, Low-Profile Steel Block Fits DPMS .308 SASS & Other .936" Diameter Barrels

Ultra-low profile steel gas block is designed to fit under extended-length free-float tubes on the DPMS .308 Semi-Auto Sniper System (SASS) barrel, and other AR-style .308 and AR-15/M16 barrels with a .936" O.D. at the gas block location. Two set screws on the underside keep the block firmly in place. Made of tough, 4140 steel for extra resistance to gas erosion.
