Real Avid AR15 Lug-Lok Upper Vise Block

The new Lug-Lok Vise Block is a new design that vastly improves on traditional clamp-style upper vises. Inserting through the the upper and into the barrel’s star chamber, this vise block gives the user a solid base to install barrels, handguards, optics, and other upper parts without worrying about damaging the upper like clamp-style vise blocks.

Additionally, 2 vise pins help hold the upper at different angles while keeping the leverage on the vise block. Compatible on AR15 uppers, this vise block protects your parts and is the smartest way to assemble your AR15.


  • Uses 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


  • Brand: Real Avid
  • Model: AR15 Upper Vise Block
  • Fit: AR-15

Nice tool

Works very well for barrel and muzzle device installations. Well made and with nice accessories that help to locate the upper and prevent it from walking around in the vise jaws.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase.
