Magpul AR15/M4 Barrel Extension Vise BEV Block


The BEV Block (Barrel Extension Vise) is an all-in-one, compact vise block tool for AR15/M4 style rifle assembly operations of barrel nuts, flash hiders, etc.

Mounts securely in a vise and provides support for both billet and forged upper receivers. Engages barrel extension with solid steel lugs and full length support shank to prevent flexing. Steel hardness is optimized for durability yet won't damage barrel extension, and Magpul Polymer is used for all other engagement surfaces to protect aluminum receiver. O-ring post uses bolt carrier for additional stability and included Pin keeps upper in proper position.

The BEV can also be turned over and used as a mag well vise block to support the lower receiver during maintenance, etc.

Made in U.S.A.

    The vise works like advertised, does not need to grab the upper. Fits inside the upper and it grabs the barrel.
