Geissele SAG 7.62 Suppressor Alignment Gage 10-260-F

Geissele SAG 7.62 Suppressor Alignment Gage 10-260-F verifies the alignment of a suppressor to the bore of a firearm barrel, catching a misalignment problem most shooters never think to check for.

This Geissele SAG 7.62 Alignment Gage works because a suppressor is usually much longer than the barrel-to-muzzle-device interface, so a small deviation at the mounting point translates into a much larger deviation at the suppressor's exit hole. Those small deviations can also compound rather than cancel out, making misalignment worse the farther down the suppressor's length it travels — a real concern on .308/7.62mm precision builds where accuracy is already the whole point.

Manufactured from hardened steel and ground 0.002" under nominal bore diameter, this Suppressor Alignment Gage is finished straight to 0.001" over its full 17" length. That length is what does the actual aligning work — the gage's own straightness carries the alignment check down the suppressor's full length rather than relying on an overly tight bore fit. This durable construction and precise dimensioning make it an essential tool for suppressor installation and ongoing maintenance.

Key Features:

• 17" length, .308/7.62mm caliber
• Hardened steel construction
• Ground 0.002" under nominal bore diameter
• Straight to 0.001" over its entire length
• Resists wear from powder residue and baffle contact
• Identifies complete pass, partial failure, and complete failure conditions
• Black finish
• Made in the USA

This suppressor alignment gage turns a guessing game into a verifiable check, catching misalignment on a .308/7.62mm platform before it becomes a baffle strike.
