Aim Sports ATUVB AR-15 Upper Receiver Vise Block Black Polymer

The Aim Sports ATUVB Upper Receiver Vise Block is a purpose-built gunsmithing tool designed to securely clamp an AR-platform upper receiver into a bench vise without crushing, distorting, or marring the receiver's finish.

Made from solvent-resistant black polymer, the ATUVB is ideal for routine cleaning, detail stripping, parts service, and reassembly. The polymer jaws cradle the upper so you can work the bolt carrier group, barrel nut, gas block, or handguard without risking damage from bare metal vise jaws.

Drop the block into your vise, seat the upper, and tighten. The ATUVB weighs just 12.7 oz and is a simple, inexpensive shop essential for any AR owner or builder.
