The Lug-Lok Upper Vise Block – AR10 is a precision-machined gunsmithing tool designed to securely hold any Mil-Spec AR10 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 AR10 assembly maintenance and accessory installation this upper vise block provides a stable safe and repeatable hold without relying on external clamping.
