This hardened polymer block inserts into the upper receiver's magazine well area, providing a solid purchase point for bench vise work without damaging the receiver's finish or chamber area.\u003c\/p\u003e\u003cp\u003eThe block's design distributes clamping pressure across the upper receiver's barrel extension recess, preventing marring of the receiver while allowing sufficient torque application for barrel nut installation and removal. Compatible with mil-spec AR-15 and M16 upper receivers in 5.56\/.223 configuration. Essential for home armorers performing barrel swaps, free-float handguard installations, or complete upper builds.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-15\/M16 Upper Receivers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Impact-Resistant Polymer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Use:\u003c\/strong\u003e Upper Receiver Workholding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bench Vise Required (Not Included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications:\u003c\/strong\u003e Barrel Installation, Muzzle Device Work, Upper Assembly\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wheeler","offers":[{"title":"Default Title","offer_id":47939716645119,"sku":"WH156224","price":65.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1306152.jpg?v=1766546288","url":"https:\/\/doublestackstore.com\/products\/wheeler-ar-armorers-vise-block-tool","provider":"Double Stack Store","version":"1.0","type":"link"}
