Geissele Automatics was established in 2004 as a manufacturer of trigger mechanisms for the AR-15 rifle. Rely on Geissele when you expect superior performance, quality, and reliability.
The Geissele Suppressor Alignment Gage (SAG) is a precision gage used to verify the alignment of a suppressor to the bore of a firearm barrel. It is important to understand that the length of the suppressor is usually much longer than the length of the barrel / muzzle device / suppressor interface geometry. A small deviation at the mounting interface means a much larger deviation of the suppressor exit hole. The deviations from nominal can also be additive which compounds suppressor misalignment.
Features and Specifications:
Manufacturer Number: 10-260
7.62 Suppressor Alignment Gage
Hardened steel ground to 0.002” under nominal bore diameter
Straight to 0.001” over its length
For the gage to yield a complete pass, there will need to be a somewhat even spacing around the SAG
Partial failure occurs when the gage is able to pass through the suppressor, but comes in to contact with the interior
Complete failure of the alignment occurs when the SAG gets stuck before it can emerge from the end of the suppressor
