REAL AVID/REVO Lug-Lok AR10 Upper Vise Block (AVAR10LLVB)

Real Avid designed an upper block that leverages the strongest part of the gun - the barrel lugs inside the star chamber. The Lug-Lok AR10 Upper Vise Block 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.
