6.5mm Suppressor Alignment Gage

The Geissele Suppressor Alignment Gage is a precision measurement tool designed to verify suppressor bore alignment before installation. Manufactured from hardened steel and ground 0.002 inches under nominal bore diameter, this gage accommodates the typical variance found in barrel bore diameters and straightness across firearms. The extended 17-inch length naturally aligns the gage to the bore without requiring an excessively tight fit, allowing technicians to detect even minor deviations at the mounting interface that would translate to larger misalignments at the suppressor exit. The hardened steel construction resists wear from powder residue exposure and prevents burring or particle embedding during the inspection process. The finely finished outer diameter maintains 0.001-inch straightness tolerance throughout its length. Suitable for 9mm applications, this gage weighs 0.5 pounds and features a 0.340-inch diameter, making it an essential tool for precision suppressor installation verification.
