Geissele 6.8mm Suppressor Alignment Gauge

The Geissele suppressor alignment gauge (SAG) is a precision instrument designed to verify the alignment of a suppressor with the bore of a firearm barrel. It is crucial to recognize that the suppressor's length typically exceeds that of the barrel, muzzle device and suppressor interface geometry. A minor deviation at the mounting interface can result in a significantly larger deviation at the suppressor's exit hole. These deviations can accumulate, exacerbating suppressor misalignment.
