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.

    Must-have Tool!

    Posted by Dave Bush on 24th May 2022

    This tool works like a champ! I purchased it to be able to change a muzzle device on an AR15. The tool locks up very solidly inside the chamber, keeping the upper/barrel extremely stable. This made changing out muzzle devices very easy. It's exactly what you would expect from Magpul. If you own AR15's you need this tool! Thank you Arms Unlimited!
