Faxon Low Profile Gas Block .625 3-Screw Nitride

The Faxon Firearms Low Profile Gas Block is an ultra-low profile, three-screw clamp gas block designed for barrels with a .625-inch diameter gas journal. Constructed from high-strength steel and finished with a nitride coating, it is intended for AR-15 platform builds where a slim gas block footprint is required. The block uses three Allen-type set screws on the underside to secure to the barrel and is offered in a skeletonized Airlite variant for reduced weight. Note that the gas tube roll pin is not included.
