This mil-spec compatible upper features a flat-top configuration with a full-length Picatinny rail for optics mounting. The billet construction allows for tighter tolerances and enhanced rigidity compared to forged uppers, while maintaining compatibility with standard AR-15 components including bolt carrier groups, charging handles, and barrel assemblies.\u003c\/p\u003e\u003cp\u003eMachined from 7075-T6 aluminum billet and finished with a hard-coat anodized surface, this upper receiver includes a brass deflector, forward assist, and ejection port cover assembly. The Gen2 design incorporates improved aesthetics with functional enhancements to the ejection port and dust cover interface. No barrel, bolt carrier group, or charging handle included—requires standard AR-15 components for completion.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlatform:\u003c\/strong\u003e AR-15\u003c\/li\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 Mil-Spec AR-15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075-T6 Aluminum Billet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Hard-Coat Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Forward Assist, Ejection Port Cover Assembly, Brass Deflector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Requires Barrel, BCG, and Charging Handle (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spike's Tactical","offers":[{"title":"Default Title","offer_id":47938903638271,"sku":"SPKSFT52B2","price":251.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2877070.jpg?v=1766535938","url":"https:\/\/doublestackstore.com\/products\/spikes-billet-upper-gen2-milspec","provider":"Double Stack Store","version":"1.0","type":"link"}
