Geissele Suppressor Alignment Gage

Precision Suppressor Alignment

The Geissele Suppressor Alignment Gage (SAG) is a precision tool designed to verify suppressor alignment to the bore of a firearm barrel. Small deviations at the mounting interface can result in significant suppressor exit hole misalignments, compounded by additive tolerances.

High-Quality Construction

• Material: Manufactured from hardened steel for exceptional durability.
• Precision Tolerances: Ground 0.002" under nominal bore diameter and straight to 0.001" over its length.
• Enhanced Surface: Hardened to resist wear, prevent burrs, and avoid embedding abrasive particles.

Optimized for Most Barrels

The Geissele SAG’s long length ensures proper alignment with the bore without requiring an overly tight fit. The 0.002" under nominal bore diameter size accommodates most barrel variations in diameter and straightness.
