Magpul BEV Block Black Polymer and Steel Barrel Extension Vise Block

Description

Product Overview

The Magpul BEV Block is a compact barrel extension vise block designed for AR15 and M4 assembly work. It mounts securely in a vise and supports consistent, non-marring alignment when installing or removing components that require barrel nut, flash hider, and related torque or adjustment operations.

Key Features

• O-ring post and pin design help keep the upper in the correct position for repeatable alignment
• Full-length support shank helps prevent flexing during barrel nut and flash hider work
• Steel lugs engage the barrel extension for solid, stable support during tightening and removal operations
• Polymer engagement surfaces protect aluminum upper receiver surfaces from damage

If you assemble or service AR15 and M4 uppers regularly, the Magpul BEV Block helps keep your work consistent while protecting critical mating surfaces.
