Real Avid Lug-Lok Upper Vise Block AR-10

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.Precision-machined to fit all Mil-Spec AR10 upper receiversEngages directly with barrel lugs inside the star chamber for maximum strengthConstructed from non-marring, aircraft-grade aluminumEliminates risk of damaging the upper receiver during high-torque applicationsLock Knob secures the rod firmly into positionDual Vise Pins allow for multiple working angles and prevent unwanted rotationDistributes torque through the steel barrel lugs, not the upper housingIdeal for AR10 building, maintenance and accessory installationProvides a stable, repeatable hold without external clampingDesigned for safe, professional-grade AR10 gunsmithing and armorer work
