The Faxon Firearms Low Profile Adjustable Gas Block (brand part number GBA-LP-750-3) is a steel .750-inch gas block built to take an AR-15’s gas system to the next level. Faxon Firearms placed the adjustment screw in a patent-pending location that avoids contact with gas port carbon, so the block stays free of seizing or fouling for consistent, hassle-free cycling in any condition. It fits any barrel with a standard .750-inch gas journal, Faxon or otherwise, and works equally well for suppressed and unsuppressed shooting. Precise screw adjustability lets a builder fine-tune cycling, recoil, and reliability to match a given upper.
