375 Caliber Suppressor Alignment Gage

This precision suppressor alignment gage from Geissele is engineered to verify critical bore alignment before installation. Manufactured from hardened steel and ground 0.002 inches under nominal bore diameter, the gage accommodates typical variations in barrel bore specifications while maintaining durability against powder residue and abrasive contact. The extended 17-inch length allows natural alignment with the bore without requiring an overtight fit, compensating for the amplified deviation that occurs over a suppressor's length compared to the mounting interface. The outside diameter is finished straight to 0.001 inches tolerance, ensuring consistent measurement accuracy. The hardened steel construction resists wear, burring, and particle embedding during inspection procedures. Designed for 9mm applications, this alignment gage represents a straightforward method to identify potential suppressor misalignment issues before they develop into performance or safety concerns. Compact at half a pound, it integrates easily into any gunsmith or serious shooter's toolkit for verification work.
