{"product_id":"geissele-super-dynamic-enhanced-sd-e","title":"Geissele Super Dynamic Enhanced (SD-E) Trigger – AR-15\/AR-10","description":"\u003cp\u003eThe Geissele Super Dynamic Enhanced (SD-E) is a two-stage trigger designed for precision shooting in AR-15 and AR-10 platforms. It delivers a clean, crisp break with minimal take-up in the first stage and a glass-rod snap in the second stage, making it ideal for marksman applications where shot control matters. This trigger bridges the gap between competition precision and duty reliability, offering repeatable performance without the light pull weights that can be problematic in high-stress environments.\u003c\/p\u003e\u003cp\u003eMachined from tool steel with a nickel-boron coating for corrosion resistance and smooth operation, the SD-E features a pull weight of approximately 3.5 pounds total (2.3 pounds first stage, 1.2 pounds second stage). Installation is straightforward for those familiar with AR trigger group removal and reinstallation—no permanent modifications required, though proper tools and safe gunsmithing practices are essential. The trigger includes all necessary pins and springs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Two-Stage Trigger Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, AR-10, and other AR-pattern rifles (mil-spec lower receivers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Nickel-Boron Coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePull Weight:\u003c\/strong\u003e Approximately 3.5 lbs (2-stage)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (gunsmithing knowledge recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Trigger assembly, hammer, springs, pins\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Geissele Automatics","offers":[{"title":"Default Title","offer_id":47943515963647,"sku":"GEI05-167","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1265961.jpg?v=1766582118","url":"https:\/\/doublestackstore.com\/products\/geissele-super-dynamic-enhanced-sd-e","provider":"Double Stack Store","version":"1.0","type":"link"}
