Product description

Real Avid Lug-Lok Upper Vise Block

Traditional 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, we 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 AR-15 upper into a bench vise.



  • Uses the strength of barrel lugs to secure upper
  • Precision machined to universally fit into all MIL-SPEC barrel lugs
  • Superior experience to old-fashioned clamp-style outer receiver blocks
  • Eliminates crushing and marring of outer receiver
  • Secure the upper at multiple optimum working angles
  • Critical functionality: torquing barrel nuts, changing flash suppressors, installing handguards, adding accessories to a Picatinny rail, building or customizing
  • Vise pin retaining holes
  • Lock knob retaining holes
  • 7075-t6 aircraft-grade aluminum
  • Star chamber locking lugs
  • 2 stainless steel vise pins
  • Alignment flange
  • Upper receiver lock knob
