Geissele Automatics 5.45mm Suppressor Alignment Rod - 17"

The Geissele 5.45mm suppressor alignment rod is a 17‑inch hardened steel gauge used to verify concentricity between a barrel bore and a mounted suppressor. It is used to detect deviation at the muzzle interface so mount geometry and baffle stacks can be inspected before live fire. The rod is ground 0.002" under nominal bore diameter and finished straight to 0.001" over its length to maintain dimensional accuracy. It is manufactured by Geissele Automatics in North Wales, Pennsylvania, United States.
