The Magpul BEV Block (Barrel Extension Vise) for AR-15/M4 is an all-in-one, compact vise block tool designed for assembly operations such as installing barrel nuts and flash hiders. This versatile tool provides support for both billet and forged upper receivers, engaging the barrel extension with solid steel lugs and a full-length support shank to prevent flexing. The BEV Block's steel hardness is optimized for durability without damaging the barrel extension, while Magpul Polymer is used for all other engagement surfaces to protect the aluminum receiver. An O-ring post utilizes the bolt carrier for additional stability, and the included pin keeps the upper in the proper position.
