Helpful Positive Review
Will save you pennies on the dollar by David, Verified Owner, May 21, 2022
I have several 5.56 rifles, some ARs, some military piston guns. I bought an OSS suppressor and put the OSS flash hiders on all them. Two had a poor alignment. Without this rod I'd have risked a baffle strike and been out $1,000+. If this rod prevent...

baffle strikes suck by m, Verified Owner, December 15, 2024
They are pricey but cheap if you consider how much it will cost to repair or replace a suppressor if it's not properly aligned. Good piece of mind item.

Muzzle devices are cool until they aren't aligned right. This rod is an essential tool that effectively checks alignment of any muzzle device. It's best used for suppressors, but I used it on my muzzle break to ensure its alignment. If you enjoy savi...

Product Info for Geissele Suppressor Alignment Rod 5.56mm, 15 in

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.image

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.
