Battle Arms Development Workhorse Low Profile Gas Block Features The Battle Arms Development Workhorse Low Profile Gas Block is machined to a .750 diameter matching the gas block journal on the vast majority of AR-15 barrels. Its low profile design allows a free float handguard to pass over the gas block without clearance issues which keeps the rifle s silhouette clean and avoids the bulk of an exposed taller gas block. A matte black finish matches the rest of a standard AR-15 s hardware so the gas block blends in rather than standing out against other components. Included low profile set screws secure the block to the barrel eliminating the need to source separate screws for installation. Battle Arms Development has built its reputation since 2009 on pushing the boundaries of small arms design and manufacturing from its headquarters in Henderson Nevada. That same attention to engineering detail carries through to a component as fundamental as a gas block which plays a critical role in cycling the rifle s action reliably. A properly fitted well-made gas block reduces the chances of gas leaks or inconsistent cycling that can plague a build using lower quality parts. For builders assembling a new upper or replacing a worn or damaged gas block the Workhorse Low Profile Gas Block is a solid straightforward component from a respected manufacturer.
