Magpul BEV Block for AR-15/M4 Upper & Lower Receivers

Overview

Magpul BEV Block Features The BEV Block mounts securely in a vise and provides stable support for both billet and forged upper receivers. Solid steel lugs engage the barrel extension while a full length support shank prevents flexing during torque applications. Steel hardness is optimized for durability while avoiding damage to the barrel extension interface. Magpul polymer is used for all other engagement surfaces to protect aluminum receivers from marring. An O ring post utilizes the bolt carrier for added stability during assembly procedures. An included pin keeps the upper receiver properly positioned for consistent and controlled installation work.
