REAL AVID SMARTFIT VISE BLCK AR15/10

Real Avid Smart Fit Vise Block, Fits AR15/AR10, Compatible with Most Vices, Gray AV1015SFVB

The 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.
