The low-profile adjustable gas block allows the shooter to use a free-floating handguard that extends over the gas port while controlling the amount of gas cycling through the weapon. This block includes two set screws to secure it in place, a lock-down screw, a steel adjustment screw, and a standard 5/64" × 5/16" gas tube roll pin.
