It delivers a clean, consistent break ideal for precision shooting, whether you're working from a prone position or engaging targets at extended range. This trigger is a direct upgrade for shooters seeking match-grade control in a duty-ready package.\u003c\/p\u003e\u003cp\u003eMachined from hardened steel with a non-reflective finish, the SSA Large Pin features Geissele's signature two-stage design: a smooth first stage that takes up slack, followed by a crisp second stage break. Total pull weight is approximately 4.5 pounds. Installation requires basic AR armorer knowledge and standard punch set—no permanent modification to the lower receiver. This is a drop-in trigger group, though first-time installers may benefit from referencing installation videos or manuals.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Two-Stage Trigger Group\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15, AR-10, and other AR-pattern rifles with .154\" (large) trigger\/hammer pin holes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Non-Reflective\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePull Weight:\u003c\/strong\u003e ~4.5 lbs (two-stage)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (Basic Armorer Skills Recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Trigger, Hammer, Disconnector, Springs, Pins\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Geissele Automatics","offers":[{"title":"Default Title","offer_id":47943512326399,"sku":"GEI05-123","price":310.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1265927.jpg?v=1766581931","url":"https:\/\/doublestackstore.com\/products\/geissele-spr-semi-auto-ssa-lrg-pin","provider":"Double Stack Store","version":"1.0","type":"link"}
