Real Avid AVAR10LLVB Lug-Lok Upper Vise Block AR-10 Aluminum

The Real Avid AVAR10LLVB Lug-Lok Upper Vise Block transforms AR-10 maintenance from a precarious balancing act into a secure, professional operation. This precision-machined aluminum fixture locks directly into the barrel extension lugs, providing rock-solid stability for upper receiver work without risking damage to your rifle's finish or components.

What Makes This Different

Unlike universal vise blocks that clamp onto the outside of receivers and risk marring or shifting, the Lug-Lok system engages the actual barrel extension lugs - the same hardened steel surfaces that lock your barrel to the upper receiver. This direct engagement eliminates movement and distributes clamping forces across the strongest part of the assembly. The natural aluminum construction won't scratch receiver finishes, while stainless steel pins provide corrosion resistance and precise fit.

Key Features

• Locks directly into barrel extension lugs for maximum stability
• Natural aluminum construction prevents finish damage
• Stainless steel pins resist corrosion and maintain precision fit
• AR-10/.308 platform specific design accommodates larger dimensions
• Standard vise jaw compatibility fits most bench vises
• Precision CNC machining ensures consistent barrel alignment
• Compact profile allows access to all upper receiver components

This vise block excels during barrel installations, muzzle device timing, gas block adjustments, and upper receiver modifications. The secure mounting eliminates the wobble and potential damage associated with external clamping methods. Gunsmiths and serious enthusiasts rely on this tool for consistent results when proper torque specifications and precise alignment are critical. The aluminum construction handles repeated use while maintaining the tight tolerances necessary for professional-grade work.
