Magpul BEV Block AR-15 Barrel Extension Vise Block Black

The Magpul BEV Block is a compact vise block for AR-15 and M4 gunsmithing work. It mounts in a vise and supports the upper receiver during assembly tasks such as installing barrel nuts and flash hiders, and it works with both billet and forged upper receivers.

The barrel extension engages with steel lugs backed by a full-length steel support shank that resists flexing. The remaining engagement surfaces are polymer to protect the aluminum receiver. An O-ring post uses the bolt carrier for stability, and an included pin keeps the upper in position. The block can be flipped over to support a lower receiver as a magwell vise block.

The BEV Block is fit for AR-15, M4 and M16 barrel extensions and is made in the U.S.A. from black Magpul polymer.
