Real Avid Lug-Lok Vise Block

The Lug-Lok Upper Vise Block – AR15 is a precision-machined gunsmithing tool designed to securely hold any Mil-Spec AR15 upper receiver by engaging directly with the barrel lugs inside the star chamber. Constructed from non-marring, aircraft-grade aluminum, it eliminates the risk of damaging the receiver during high-torque operations. The Lug-Lok rod locks into the strongest structural point of the rifle, while the Lock Knob and dual Vise Pins ensure secure, adjustable positioning at multiple working angles. Ideal for AR15 assembly, maintenance and accessory installation, this upper vise block provides a stable, safe and repeatable hold without relying on external clamping.
