15" 5.56mm Suppressor Alignment Rod

This Geissele Suppressor Alignment Rod is a precision measurement tool designed to verify proper suppressor alignment to the barrel bore. The gauge accommodates 5.56mm specifications with a 0.2175" outer diameter and fits AR-15 platforms and universal applications. At 15 inches in length and weighing just 0.020 lbs, it provides accurate centerline alignment verification by accounting for multiple critical factors including barrel thread offset and angular alignment, barrel shoulder perpendicularity to threads, muzzle device internal geometry alignment, and suppressor mounting ID geometry to bore alignment. This new alignment rod assists in diagnosing potential issues with suppressor concentricity and helps ensure optimal performance. Essential for precision shooters and gunsmiths requiring verification of suppressor mounting geometry before installation.
