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

The Aim Sports ATUVB Upper Receiver Vise Block transforms AR-15 maintenance from a frustrating struggle into precise, controlled work. This black polymer vise block secures upper receivers firmly without damage, enabling proper torque application and preventing costly mistakes during barrel installation or removal.

What Makes This Different

Unlike generic aluminum blocks that can mar receiver surfaces, this polymer construction grips securely while protecting the finish. The precision-molded design matches AR-15 upper receiver dimensions exactly, distributing clamping pressure evenly across the entire surface. Standard vise jaws often slip or concentrate pressure in small areas, leading to scratched receivers or improper barrel alignment.

Key Features

• Black polymer construction prevents marring of receiver finishes
• Precision-molded to match AR-15/M16 upper receiver specifications
• Compatible with standard bench vises and gunsmith workbenches
• Provides stable platform for barrel nut installation and removal
• Lightweight design stores easily in toolboxes
• Non-slip surface texture maintains secure grip under torque
• Universal fit accommodates mil-spec and commercial receivers

Professional gunsmiths rely on proper fixturing to achieve consistent results. This vise block enables accurate barrel timing, prevents receiver damage during high-torque operations, and maintains alignment throughout the assembly process. The polymer material withstands repeated use without cracking or deforming, making it suitable for both occasional home builders and high-volume shops.
