The Real Avid AVAR10SFVBS Smart-Fit AR-10 Vise Block Sleeve eliminates the frustration of loose-fitting vise blocks that can damage receivers during maintenance and builds. This precision-engineered sleeve system adapts to fit both AR-15 and AR-10 platforms with its innovative expansion block technology.
What Makes This Different
Unlike traditional one-size-fits-all vise blocks that rely on foam padding or shims, the Smart-Fit system uses a mechanical expansion mechanism to create a secure, non-marring grip inside the receiver extension. The dual-platform compatibility means gunsmiths and enthusiasts can service multiple rifle types with a single tool. The red and gray color coding helps identify proper orientation and prevents installation errors.
Key Features
- Mechanical expansion block adjusts for precise fit in AR-15 and AR-10 receivers
- Non-marring polymer construction protects receiver finish during clamping
- Color-coded design (red/gray) ensures proper installation orientation
- Eliminates receiver flex and movement during upper/lower separation
- Compatible with standard bench vises and gunsmithing fixtures
- Reversible design accommodates different receiver extension lengths
- Textured grip surfaces prevent slippage under torque loads
The Smart-Fit system maintains consistent clamping pressure across different manufacturer specifications, from mil-spec to commercial buffer tube dimensions. Professional armorers rely on this tool for barrel installations, muzzle device timing, and upper receiver work where precise alignment matters. The expansion mechanism distributes clamping force evenly, preventing the stress concentrations that can crack aluminum receivers.
