The GO2 Extreme Duty .750 low profile block was designed to offer an additional boss for pinning the gas block. This prevents the possibility of weapon malfunctions caused when set screws loosen from high heat generated on platforms that are often operated at a demanding pace. The .750 bore is held to high tolerances to allow for snug fit to most AR15 barrels and M4 carbines with .750 gas block bosses. Enhance your platform with a GO2 Extreme Duty gas block today.
Optional pinning lug allows end user to pin block for an ultimate rock-solid installation.
