The Strike Industries AR Low Profile Gas Block (brand part number SI-AR-LPGB) is a .750 inch steel gas block built to fit under nearly any AR-15 free-float handguard. Strike Industries combines a lightweight, cost-effective design with black nitride-finished steel construction, giving it the durability to handle sustained fire without the bulk of a traditional gas block. It’s purpose-built for extended-length free-float setups where handguard clearance is tight, letting you run a slimmer rail without machining or grinding. The block ships with two M5x0.8x6mm set screws and one 2mm x 8mm spring pin, so everything needed for installation is in the box.
