Real Avid Smart-Fit AR-10 Vise Block Sleeve Red/Gray w/ Expansion Block - Fits AR-15 & AR-10

The Real Avid Smart-Fit AR-10 Vise Block Sleeve is an innovative gunsmithing tool that delivers a precise, slop-free fit on large-frame AR-pattern lower receivers. The sleeve slides and locks directly onto any Real Avid Smart-Fit AR-15 vise block, instantly converting it into a snug-fitting holder for AR-10A-pattern lowers including the DPMS LR-308 and SR-25. The included expansion block lets a single setup work with both AR-15 and AR-10 magazine wells, so there is no need to swap fixtures when moving between platforms at the bench.

Built from durable polymer in a high-visibility Red and Gray two-tone finish, the sleeve is gentle on finished receivers and stands up to repeated bench work. It accepts most Mil-Spec and commercial-spec AR-10 lower receivers, making it the ideal workholding solution for the gunsmith or home builder who wants a clean, wobble-free setup without buying a second dedicated block. Whether you are diagnosing a trigger group, swapping components, or performing general lower disassembly, the Smart-Fit sleeve keeps the receiver solidly indexed in the vise.
