Real Avid AR15 Lug-Lok Upper Vise Block

The RealAvid AR15 Lug-Lok Upper Vise Block provides stability when working on your AR15. Designed to lock directly into the barrel extension lugs, this tool provides exceptional strength and support without clamping onto the receiver’s exterior - eliminating the risk of cosmetic or structural damage.

Its adjustable vise pin system offers multiple secure working angles, giving you optimal positioning for any task. Precision-machined from aluminum that’s softer than steel, the Lug-Lok engages the lugs safely while maintaining a firm, reliable hold. A four-position lock knob ensures consistent and positive engagement every time.
