ProMag PM245 AR-10 Lower Receiver Vise Block .308/7.62 NATO

The ProMag PM245 Lower Receiver Vise Block eliminates the risk of crushing or marring your AR-10 lower receiver during maintenance and assembly work. This precision-molded polymer tool fits securely into the magazine well, providing a stable platform for torquing barrel nuts, installing handguards, and performing detailed gunsmithing tasks on .308 Winchester and 7.62x51mm NATO rifles.

What Makes This Different

Unlike generic vise blocks that rely on external clamping pressure, the PM245 locks directly into the magazine well for maximum stability without stress points. The polymer construction won't scratch or damage your receiver's finish, while the reinforced design handles the torque requirements of barrel nut installation. This eliminates the wobble and potential damage associated with improvised clamping methods.
