Lug-Lok® Upper Vise Block

Advanced Thinking, AR15 Upper BlockTraditional 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, Real Avid 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. The result – the safest, easiest and smartest way to lock down an AR15 upper into a bench vise.The Safest and Smartest Way to Lock Down An AR15 Upper Into a Bench Vise.Uses the strength of barrel lugs to secure upperPrecision machined to universally fit into all MIL-SPEC barrel lugsSuperior experience to old-fashioned clamp-style outer receiver blocksEliminates crushing and marring of outer receiverSecure the upper at multiple optimum working anglesCritical functionality: torquing barrel nuts, changing flash suppressors, installing handguards, adding accessories to a picatinny rail, building or customizingProduct Features: Vise Pin Retaining Holes Lock Knob Retaining Holes 7075-T6 Aircraft Grade Aluminum Star Chamber Locking Lugs Alignment Flange Upper Receiver Lock Knob 2 Stainless Steel Vise Pins
