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. The Geissele SAG is manufactured from hardened steel that has been ground 0.002” under nominal bore diameter. The outside diameter of the SAG is finely finished and straight to 0.001” over its length. Geissele hardens the SAG so that it will not wear by sliding exposure to abrasive powder residue, pull burrs if it slides against misaligned baffles nor allow abrasive particle to imbed into the surface of the gage. There can be a wide variation in barrel bore diameters and bore straightness. 0.002” under nominal bore diameter has been found to be the best size of the SAG that will fit most barrels. The long length of the SAG aligns the gage to the bore; it is not necessary to have a very tight fitting gage with the long length of the Geissele SAG.

Full Description

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.


Additional Information

Notes Suppressor alignment is determined by several factors: 1. Centerline alignment (offset and angular) of the barrel threads to the bore. 2. Perpendicularity of the barrel shoulder to the threads. 3. Alignment of the muzzle device’s internal diameter threads and torque shoulder to the suppressor attachment geometry. 4. Alignment of the suppressor mounting ID geometry to the bore of the suppressor.

Worth every penny - Tom

Slapped my new Sandman-S on my rifle and did a quick visual. Looked a little wonky but wasn't sure if it was my eyes (getting old sucks). A little voice in my head said "don't shoot it stupid" and I surprisingly listened. Ordered the 7.62 rod and when it arrived ran it down the bore and sure enough, its off center. Not sure if its close enough to get a strike, but why risk it?

peace of mind with excellent tools - Michael

My experience so far with the alignment tool has been a great one. I started out doing my own work not too long ago and wanted to have a guarantee that I did the right threading pattern for my 308. Other than that it came out just fine and now I can let it rest. Most would say just eyeball it, but I prefer it to be precise and on the money on the first go. No one wants to see $1,000 tragedy happen, that's including the tax stamp.
