Breakthrough Clean AR-15 Lower Receiver Vise Block

The Breakthrough Clean AR-15 Lower Receiver Vise Block slides into the magazine well and gives you a solid clamping surface for bench work. A built-in pivot lock holds the lower in position. That frees both hands for tools and small parts.

Clamping the block instead of the receiver keeps vise jaws off the finish. It's useful for trigger installs, buffer tube work and detailed cleaning. The fit in the magwell keeps the lower from shifting.

Use it with a bench vise that has soft jaws for extra protection. Pair it with an armorer's wrench for buffer tube and castle nut work. Keep the workpiece supported and follow the component manufacturer's torque guidance when the maintenance job involves threaded parts. Browse more gun cleaning and maintenance.
