Magpul Industries BFI-WW Accessory Blue Filter for 1.25" Diameter Bezels Black AR-15 MAG538-BLK
The Magpul BEV Block (Barrel Extension Vise) takes the worry out of applying torque to your upper when installing and removing barrel nuts and muzzle devices. Supporting both Billet and Forged upper receivers, the BEV engages the barrel extension with solid steel lugs, preventing torque from being transferred to your softer aluminum receiver. A full length support shank prevents flexing and is seated into Magpul Polymer to protect the your receiver. An O-Ring port uses the bolt carrier for additional stability, and an included pin is used to triply ensure the receiver stays in position.
The multi-purpose BEV can also be flipped and used as a mag well vise block to support the lower receiver during maintenance.
