【Compact Vise Block. Solid Steel Lugs. Full-Length Steel Shank. High-Quality Polymer Body. Supports Upper & Lower Receivers. Made in USA.】

The Magpul BEV Block (Barrel Extension Vise) is a compact yet heavy-duty vise block tool designed for professional AR15/M4 assembly operations, such as installing barrel nuts and muzzle devices. By engaging the barrel extension with solid steel lugs, the BEV Block ensures that the torque applied during assembly is absorbed by the tool’s steel core rather than the aluminum receiver.

Key Features & Technical Benefits:

• 🛡️ Rigid Steel Core: Features solid steel lugs and a full-length steel support shank to prevent flexing and ensure a rock-solid interface with the barrel extension.
• 🛠️ Receiver Protection: While the core is steel, all other engagement surfaces are made from Magpul’s proprietary high-quality polymer to protect the finish of your forged or billet upper receivers.
• 🎯 Enhanced Stability: The tool includes an O-ring post that utilizes the bolt carrier for additional internal stability and a dedicated pin to keep the upper receiver in the perfect orientation during work.
• 🔄 Versatile Utility: The BEV Block is truly multi-functional; simply flip it over to use it as a mag well vise block, providing a secure platform for lower receiver maintenance and cleaning.
• Built to Last: Proudly Made in the U.S.A., with steel hardness optimized for maximum durability without risking damage to critical firearm components.
