Machined from 7075-T6 aluminum, this flat-top upper features M4 feed ramps for reliable feeding with modern ammunition and accepts standard AR-15 bolt carrier groups and barrels. The MUR design eliminates the forward assist and shell deflector, reducing weight and providing a clean, ambidextrous profile suitable for left- and right-handed shooters.\u003c\/p\u003e\u003cp\u003eThe upper is finished in Black Anodized for corrosion resistance and includes a brass deflector. Because the MUR uses a non-standard profile, it requires a proprietary handguard mounting system or free-float handguards that clamp directly to the barrel nut. No barrel, bolt carrier group, charging handle, or handguard is included. Installation requires standard AR-15 upper receiver tools and headspace verification.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Billet Upper Receiver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Lower:\u003c\/strong\u003e AR-15 \/ Mil-Spec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeed Ramps:\u003c\/strong\u003e M4 Style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Flat-Top Picatinny Rail, No Forward Assist, Ambidextrous Design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Upper Receiver Only (No BCG, Charging Handle, or Barrel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires Barrel, BCG, Charging Handle, and Compatible Handguard System\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VLTOR Weapon Systems","offers":[{"title":"Default Title","offer_id":47939096248575,"sku":"VLTMUR-1AB","price":256.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1302780.jpg?v=1766539308","url":"https:\/\/doublestackstore.com\/products\/vltor-mur-mod-upper-rcvr-basd-blk","provider":"Double Stack Store","version":"1.0","type":"link"}
