{"product_id":"magpul-bev-block-ar15-m4","title":"Magpul BEV Block","description":"\u003cp\u003eBarrel Extension Vise. It grabs the barrel extension with steel lugs and a full-length support shank, so the torque of a barrel nut or a flash hider goes into steel instead of into a flexing upper. The steel hardness is set to hold up without marking the extension, and every surface that touches aluminum is polymer. An O-ring post uses the bolt carrier for stability and the included pin keeps the upper in position.\u003c\/p\u003e\n\u003cp\u003eFits billet and forged uppers. Turn it over and it is a mag well block for working on the lower. Made in the USA.\u003c\/p\u003e\n\u003cp\u003eProduct photography may show a representative example rather than the exact item shipped.\u003c\/p\u003e","brand":"Magpul Industries","offers":[{"title":"Default Title","offer_id":48782839644350,"sku":"MAG536-BLK","price":47.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/2020\/0126\/files\/MAG536-BLK-1.jpg?v=1787612393","url":"https:\/\/dirtyciv.com\/products\/magpul-bev-block-ar15-m4","provider":"Dirty Civilian Shop","version":"1.0","type":"link"}
