Real Avid Lug-Lok AR-15 Upper Vise Block

Get smart about the way you work on your firearm with the Lug-Lok™ Upper Vise Block. The Lug-Lok™ Vise Block utilizes the strength of barrel lugs to safely secure your upper receiver while you work, rendering clamp-style blocks obsolete. The non-marring, aircraft-grade aluminum block slides through the upper receiver and into the star chamber of your barrel. This takes the pressure from torquing away from weak, damage-prone parts and puts it squarely on the steel lugs. Adjustable vise pins hold the block at the optimal working angle, and the lock knob ensures the upper receiver stays exactly where you want it. Fits 5.56/.223 AR-15s 7075-T6 aircraft-grade aluminum construction Non-marring Precision-milled lugs fit solidly into the star chamber Vise pins allow you to position your upper receiver at any angle Lock knob keeps the upper in place
