Real Avid Smart-Fit AR-10/AR-15 Vise Block Sleeve with Expansion Block - Red/Gray

The Real Avid Smart-Fit AR-10/AR-15 Vise Block Sleeve with Expansion Block is a gunsmith's answer to working on large-frame AR platforms without the frustration of an ill-fitting setup. This sleeve slides over the Real Avid Smart-Fit AR15 Vise Block and transforms it into a dedicated AR-10 workstation, eliminating the wobble and movement that turns detailed lower-receiver work into a wrestling match. Whether you're swapping trigger groups, installing a new grip, dropping in a buffer tube, or servicing critical components, a rock-solid hold makes the job faster and safer.

Built for real gunsmithing tasks, the sleeve lets you work on an inverted lower receiver—giving you unrestricted access to the underside of your gun without repositioning. That flexibility matters when you're chasing tight tolerances on a precision build or just trying to get a clean sight picture on stubborn fasteners. The expansion block mechanism ensures a snug, repeatable grip that holds even during the kind of wrenching and tapping that separates casual work from serious projects.

If you already own a Real Avid Smart-Fit AR15 Vise Block, this sleeve is the economical route to AR-10 capability. If you're building an AR gunsmithing kit from scratch, it's a smart modular choice that scales with your work. Available in red and gray, it's as much a shop staple as a quality bench vise.
