50mm Suppressor Alignment Gage

The Geissele Suppressor Alignment Gage is a precision measurement tool designed to verify suppressor bore alignment relative to firearm barrel centerlines. Manufactured from hardened steel and ground 0.002 inches under nominal bore diameter, this gage accommodates typical barrel bore variations while resisting wear from powder residue and baffle contact. The 17-inch length naturally aligns the tool to the bore axis, eliminating the need for an excessively tight fit. The finely finished exterior maintains straightness to 0.001 inches along its length, ensuring accurate readings. This specification addresses a critical concern: small deviations at the suppressor mounting interface translate to significantly larger deviations at the suppressor exit, particularly when multiple tolerances compound. The 9mm caliber gage weighs 0.5 pounds and measures 0.34 inches in both width and height, making it a compact yet effective tool for suppressor verification and installation procedures. One unit included.
