The BEV Block (Barrel Extension Vise) is a must-have tool for anyone looking to perform assembly operations of barrel nuts, flash hiders, and other AR15 / M4 parts. This compact vise block is an all-in-one solution that will provide you with the assistance you need in performing these tasks.

The BEV Block is designed to mount securely in a vise, offering robust support for both billet and forged upper receivers. It engages the barrel extension with solid steel lugs and a full-length support shank to prevent flexing, ensuring maximum durability even when engaged in heavy-duty tasks.

In addition, the BEV Block has been optimized to protect the aluminum receiver by using Magpul Polymer on all other engagement surfaces. The steel used in the block's design is hardened to a level that ensures durability while also avoiding damage to the barrel extension.

The BEV Block comes equipped with an o-ring post that uses the bolt carrier for additional stability. This design feature, combined with the included pin, ensures that the upper stays in the proper position while you work.

Finally, the BEV Block is so versatile that it can be flipped over and used as a mag well vise block to support the lower receiver for maintenance or other operational needs.

Weighing in at only 11.2 oz., the BEV Block is a lightweight and highly portable tool that you can take with you wherever you go. Furthermore, it is proudly made in the USA.

In conclusion, the BEV Block is a superior product when compared to competing vise blocks. Its solid steel lugs and full-length support shank provide unparalleled stability, while the use of Magpul Polymer serves to protect the aluminum receiver. Whether you're a professional gunsmith or a hobbyist, the BEV Block is the ideal tool for your AR15/M4 assembly operations.
