6mm Suppressor Alignment Gage

The Geissele Suppressor Alignment Gage is a precision steel instrument designed to verify suppressor bore alignment with firearm barrels. Constructed from hardened steel and ground to 0.002 inches under nominal bore diameter, this tool prevents wear from powder residue and resists burring when checking misaligned baffles. The exterior diameter is finished straight to 0.001 inches tolerance, ensuring reliable measurements across its extended length. This 9mm gage measures 17 inches long and weighs approximately half a pound, providing sufficient length to properly align with most barrel bore variations without requiring an excessively tight fit. The extended design compensates for small deviations at the mounting interface that would otherwise compound into larger misalignment at the suppressor exit. Available in black finish, this tool is essential for precision suppressor setup and verification work.
