Lug-Lok Upper Vise Block

Uses strength of barrel lugs to secure upper Secure the upper at multiple optimum working angles Critical functionality: torquing barrel nuts, changing flash suppressors, installing handguards, adding accessories to a picatinny rail, building or customizing
Traditional clamp-style upper blocks fit poorly and can exert enough inward pressure to damage the receiver when applying torque to a barrel nut or flash suppressor. That*s bad design. So, we designed an upper block that leverages the strongest part of the gun * the barrel lugs inside the star chamber. The Lug-Lok is precision machined and precisely fits into all Mil-Spec uppers. It mates perfectly with the barrel lugs, while allowing you to rotate the upper to be able to work on different sides. There are 2 vise pins that allow you to hold the upper at multiple working angles and prevent unwanted rotation during high torque application. The lock knob keeps Lug-Lok seated into the barrel lugs. The result * the safest, easiest and smartest way to lock down an AR15 or AR10 upper into a bench vise. Choose AR10 or AR15 platform below.
