{"product_id":"geissele-lpk-ultra-duty-ddc","title":"Geissele Automatics Ultra Duty Lower Parts Kit – AR-15","description":"\u003cp\u003eThe Geissele Ultra Duty Lower Parts Kit provides all the essential components needed to complete an AR-15 lower receiver, minus the trigger group and pistol grip. This kit is designed for builders who already have a preferred trigger and grip, or who want to install those components separately. Geissele engineers these parts to the same exacting standards as their precision triggers, ensuring reliable function and proper fit.\u003c\/p\u003e\u003cp\u003eManufactured from mil-spec materials with a Desert Dirt Color (DDC) finish on select components, this kit includes the bolt catch, magazine release, and safety selector with their respective springs and detents. All parts are made in the USA. Installation requires standard AR-15 armorer's tools and basic mechanical aptitude—no professional gunsmithing required for most builders, though detent installation can be tricky for first-timers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Lower Parts Kit (LPK) without trigger or grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 platform lower receivers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Mil-spec steel components\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Desert Dirt Color (DDC) on select parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in with standard tools; detent pins require care\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Bolt catch assembly, magazine release assembly, safety selector assembly, buffer retainer, springs, and detents (does not include trigger group or pistol grip)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Geissele Automatics","offers":[{"title":"Default Title","offer_id":47943522779391,"sku":"GEI05-435S","price":158.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5492130.jpg?v=1766582838","url":"https:\/\/doublestackstore.com\/products\/geissele-lpk-ultra-duty-ddc","provider":"Double Stack Store","version":"1.0","type":"link"}
