MAGPUL BEV BLOCK – AR15/M4

The BEV Block (Barrel Extension Vise) is a multi-functional, compact clamping tool for AR15/M4 weapon assembly operations such as installing barrel nuts and flash suppressors.

It securely mounts to the clamp and provides support for both billet and casting uppers. The BEV Block locks the barrel extension with sturdy steel washers and a full-length support arm to prevent flexing. The steel hardness is optimized for durability, but it won't damage the barrel extension, and Magpul polymer is used in all other contact areas to protect the aluminum receiver. An O-ring pin uses a moving latch for added stability, and an included pin holds the upper in place.

The BEV Block can also be flipped and used as a magazine space block to support the lower section during maintenance.
