Aim Sports Upper Receiver Vise Block, Black Polymer, AR-Platform

The Aim Sports Upper Receiver Vise Block (brand part no. ATUVB) is a black polymer block built to safely clamp an AR-platform upper receiver into a bench vise for cleaning, service, or assembly work. Aim Sports molded the block to match the upper receiver’s internal geometry, spreading clamping pressure evenly so the vise jaws don’t crack or deform the receiver. That protection matters most when you’re torquing a barrel nut or working on the gas system, jobs that demand a receiver held rock solid. It’s an inexpensive way to protect an investment you’ve already made in your rifle build.

Key Specifications

• Molded from black polymer to match the internal contours of an AR-platform upper receiver.
• Spreads clamping pressure evenly to prevent vise damage to the receiver during service.
• Sized at about 4.5 inches, fitting standard AR-platform upper receivers.

Frequently Asked Questions

Why not just clamp the upper directly in a vise? Clamping an upper receiver directly risks cracking or deforming it; this block spreads pressure evenly across the receiver’s internal geometry to prevent damage.

What jobs is this useful for? It’s built for any bench work that needs the upper held steady, including barrel nut torquing, gas system service, and general cleaning.
