Real Avid Smart-Fit AR-15 Lower Receiver Vise Block with AR-10 Adapter Sleeve

The Real Avid Smart-Fit AR15 Vise Block and Vise Block Sleeve for AR10, DPMS LR-308 and SR-25 is the best lower receiver vise block you'll ever use. Magwell sizes have a notoriously wide range of tolerances, and traditional blocks create wiggle and wobble on a gun vise. Smart-Fit's design solves that. It expands to fit all MIL-SPEC AR15s, AR10s and similar magwells, making loose, sloppy-fitting blocks a thing of the past. Insert the block into the magazine well and simply rotate the adjustment handle to tighten the fit. This block can also be used with an inverted lower receiver to work on pistol grips or allow easy access to the underside of your AR.
