Real Avid Lug-Lok Upper Vise Block for AR-10 - 7075-T6 Aluminum w/ Stainless Steel Pins

The Real Avid Lug-Lok Upper Vise Block is a shop fixture purpose-built for working on AR-10 upper receivers. Precision-machined from 7075-T6 aluminum with stainless steel pins, the block engages directly with the barrel lugs inside the star chamber, indexing on the strongest part of the receiver so you can torque barrel nuts, swap handguards, or service the bolt and gas system without relying on soft jaws.

Because the Lug-Lok locates on the lugs themselves, the upper can be rotated from lug to lug while held in the vise, exposing every side of the receiver for the work at hand. Two stainless steel vise pins seat in standard vise jaws and keep the block from twisting under load. The natural aluminum finish keeps weight low and resists corrosion between builds.

Designed exclusively for the AR-10 platform, the Lug-Lok fits all Mil-Spec AR-10 uppers and is intended specifically for this pattern - it is not a cross-fit with the smaller AR-15 receiver. Vise block only; receiver and vise are sold separately.
