Important Fitment & Safety Information
Due to barrel manufacturing tolerances and machining variables outside Fulton Armory’s control, proper alignment cannot be guaranteed on every barrel.
Fulton Armory assumes no responsibility for adapter misalignment resulting from barrel spline or thread machining defects. Each adapter is individually inspected and gauged using USGI-spec barrels and gauges prior to shipment.
Bore alignment must be verified before firing. Fulton Armory shall not be held liable for damage resulting from firing a weapon without first verifying proper bore alignment.
Warranty claims are evaluated on a case-by-case basis after the adapter has been returned to Fulton Armory and inspected.
