Real Avid Lug-Lok Upper Vise Block for AR-15

The Real Avid Lug-Lok Upper Vise Block is a precision-machined, aircraft-grade aluminum tool designed to secure AR-15 upper receivers by engaging the star chamber and barrel lugs. Unlike clamp-style blocks that can exert inward pressure on the receiver, the Lug-Lok transfers torque to the steel barrel lugs to reduce the risk of receiver damage while performing maintenance. Adjustable stainless-steel vise pins and a lock knob let you set and secure multiple working angles, preventing unwanted rotation during high-torque applications. Intended for gunsmithing, maintenance, and assembly tasks on compatible AR-15 uppers, it offers a non-marring solution for bench work.
