Magpul AR-15 BEV Barrel Extension Vise Block

The Barrel Extension Vise (BEV) is a versatile, all-in-one tool for working on AR-15 and M4 upper receivers. This compact vise block securely holds the barrel extension using solid steel lugs and a full-length support shank, which prevents any flexing. By doing so, it ensures that all torque from installing or removing barrel nuts and muzzle devices is applied directly to the barrel, not the more fragile aluminum receiver.

The Magpul BEV mounts easily in a bench vise and is compatible with both billet and forged upper receivers. Its steel components are specially hardened to be durable without damaging the barrel extension. All other contact points are made from a tough Magpul polymer to protect your receiver's finish.

Features:

• Compatible with AR-15/M4 upper and lower receivers
• Steel lugs engage barrel extension securely
• Full-length steel support shank for strength
• Magpul polymer surfaces protect aluminum receivers
• O-ring post stabilizes with bolt carrier
• Includes pin to hold upper receiver in place
• Can be used as a magwell vise block for lower receivers
• Weight: 11.2 oz

For extra stability, the BEV uses an O-ring post that engages with the bolt carrier, and a separate pin holds the upper receiver in the correct position. This tool can also be flipped over and used as a mag well vise block, providing solid support for your lower receiver during maintenance and other tasks.
