The Barrel Extension Vise is an all-in-one, compact vise block for the AR-15/M4. Takes the worry out of applying torque to your upper when installing and removing barrel nuts and muzzle devices by engaging the barrel extension with solid steel lugs and a full-length support shank to prevent flexing. This prevents torque from being transferred to the softer aluminum receiver.Mounts securely in a vise and provides support for both billet and forged upper receivers. Steel hardness is optimized for durability yet won't damage barrel extension, and Magpul Polymer is used for all other engagement surfaces to protect the aluminum receiver. An O-ring post uses the bolt carrier for additional stability and an included pin keeps the upper receiver in proper position. The BEV may also be turned over and used as a mag well vise block to support the lower receiver during maintenance, etc.Magpul continues to grow and develop based on innovation, simplicity, and efficiency. At Magpul, mission driven requirements inform their product design, materials, and manufacturing, focusing on efficiency without sacrificing quality or performance.
