Magpul BEV Block

The BEV Block (Barrel Extension Vise) is your go to AR Tool. Fits into a compact vice to aid in assembly operations of the barrel nuts, flash hiders, etc. Works on both billet and forged upper receivers while engaging the barrel extension with solid steel lugs to provide full support to prevent flexing. The Steel harness has been optimized for durability and won’t damage or ramps. All other surfaces aside, are made of Magpul Polymer to protect damage to your aluminum receiver.  O-ring post uses bolt carrier for additional stability and included Pin keeps upper in proper position. The BEV can also be turned over and used as a mag well vise block to support the lower receiver during maintenance, etc.
