Real Avid Lug-Lok AR-15 Upper Vise Block Silver Aluminum

The Real Avid Lug-Lok Upper Vise Block is a purpose-built AR-15 gunsmithing tool designed to hold a barreled upper receiver securely in a bench vise during assembly, maintenance, and accessory installation. Machined from non-marring, aircraft-grade aluminum with a silver finish, this block replaces traditional clamp-style jigs by locking directly into the upper receiver's barrel extension, supporting the receiver on its barrel lugs rather than squeezing the exterior.

The defining feature of the Lug-Lok is full 360-degree working access. Because the block engages the receiver's barrel lugs rather than clamping the outside of the receiver, you can rotate the barreled upper from lug to lug to reach every side of the assembly without ever removing it from the vise. Two included vise pins engage the receiver through multiple retaining holes, letting you set and change clamping angles quickly as the job demands, keeping the upper rock-solid while you work.

Designed specifically for the 5.56 NATO / .223 Remington AR-15 upper receiver, the Lug-Lok is a bench-shop staple for builders, gunsmiths, and home armorers. The non-marring aluminum protects the receiver finish from clamp-induced damage, while the rigid block geometry provides the solid hold you need for proper work. Whether you are building a complete upper, installing accessories, or performing routine maintenance, the Real Avid Lug-Lok Upper Vise Block delivers safe, repeatable, all-angle access to the AR-15 upper.
