Real Avid Lug-Lok Upper Vise Block for AR-10 - AVAR10LLVB

Product Features & Specifications

Real Avid AVAR10LLVB Lug-Lok Upper Vise Block Natural Aluminum w/ Stainless Steel Pins for AR-10

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.
