Real Avid Lug-Lok Upper Vise Block AR-15

Smart Upper Receiver Work Starts Here

The Real Avid Lug-Lok Upper Vise Block represents a fundamental shift in how you should approach AR-15 upper receiver maintenance and assembly. Rather than relying on potentially damaging clamp-style blocks, this design leverages the inherent strength of your barrel's locking lugs—the strongest part of the upper receiver.

How It Works

The non-marring, aircraft-grade aluminum block slides through your upper receiver and seats directly into the star chamber of your barrel. This engineering approach distributes torquing pressure where it belongs: on hardened steel lugs, not on vulnerable receiver components.

Key Features

• Lug-based design — Transfers all working pressure to barrel lugs, eliminating stress on weak points
• Aircraft-grade aluminum construction — Lightweight yet rigid, with a satin finish that won't damage your receiver
• Adjustable vise pins — Position the block at your preferred working angle
• Integrated lock knob — Keeps your upper receiver exactly where you need it
• Included hardware — Two stainless steel vise pins for secure mounting
• Universal compatibility — Works with standard AR-15 style uppers in .223/5.56 caliber

Why This Matters

If you've ever worried about marring your upper receiver or damaging critical components while working, the Lug-Lok eliminates that concern. This is the thinking gunsmith's choice for professional-grade upper receiver work.
