This magwell frame acts as the foundation for the UXR modular lower system, providing a rigid magazine interface and trigger pocket while allowing configuration flexibility through interchangeable grip modules and stocks. Shooters building or upgrading a .308 AR platform benefit from the precision fit and enhanced ergonomics of the UXR system.\u003c\/p\u003e\u003cp\u003eMachined from billet aluminum with a hard-coat anodized finish, the UXR MD Frame features ambidextrous controls and a flared magwell for faster reloads under stress. Installation requires basic AR-15\/AR-10 assembly knowledge and standard tools—no gunsmithing required for the frame itself, though complete lower assembly involves installing trigger group, buffer system, and grip module per manufacturer specifications. Compatible with mil-spec AR-10 upper receivers and DPMS-pattern magazines.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Billet Lower Magwell Frame\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e .308 Win\/7.62 NATO AR-10 Pattern Rifles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Billet Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Hard-Coat Anodized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (Basic AR Assembly Knowledge Required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Magwell Frame (Grip Module and Internal Parts Sold Separately)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Primary Weapons Systems","offers":[{"title":"Default Title","offer_id":47938878046463,"sku":"PWSUXR-MW-AR10","price":129.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/4889341.jpg?v=1766534925","url":"https:\/\/doublestackstore.com\/products\/pws-uxr-magwell-md-frame-308-ar10","provider":"Double Stack Store","version":"1.0","type":"link"}
