Geissele Automatics .375mm Suppressor Alignment Rod - 17"

The Geissele .375mm Suppressor Alignment Rod is a precision 17-inch hardened steel gauge designed to verify alignment between the barrel bore and an attached suppressor. It identifies even minor deviations at the muzzle interface, allowing users to inspect mount geometry and baffle clearance before firing. Each rod is ground 0.002" under nominal bore diameter and finished straight to within 0.001" across its full length for consistent accuracy. Manufactured by Geissele Automatics in North Wales, Pennsylvania, it provides a dependable reference tool for suppressor setup and inspection.
