That two-stage discipline lets you prep the trigger and commit only when the sights say so, which is why two-stage designs dominate serious marksmanship and precision use. Geissele builds it for hard use, with full-power springs for dependable ignition.\u003c\/p\u003e\u003cp\u003eMachining, materials and quality control are where Geissele earned its name: every trigger is built to tolerances that make the pull feel identical on round one and round ten thousand.

That includes UK straight-pull AR-15 builds, where a clean two-stage break is the single biggest change you can make to how the rifle shoots, and the SSA's heavier, more forgiving weight suits a rifle used in gloves and in poor weather. Large-pin and some proprietary receivers are not compatible — confirm your pin size before ordering. A straightforward armourer-level install; always verify function and safety checks after fitting.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePlatform\u003c\/th\u003e\n\u003ctd\u003eAR-15 \/ M4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFits\u003c\/th\u003e\n\u003ctd\u003eMil-Spec lower receivers with .154 in trigger and hammer pins\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eTwo-stage trigger\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMade in\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eGeissele Automatics\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003e05-101\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eThe benchmark two-stage. \u003cstrong\u003eOrder the Geissele SSA today\u003c\/strong\u003e — imported from the USA with all duties paid by us and dispatched tracked from the UK in 7–10 business days, with nothing to pay on delivery.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eExplore more:\u003c\/strong\u003e all \u003ca href=\"\/collections\/rifle-triggers\"\u003eRifle Triggers\u003c\/a\u003e, \u003ca href=\"\/collections\/ar-15-parts-accessories\"\u003eAR-15 Parts \u0026amp; Accessories\u003c\/a\u003e or browse all \u003ca href=\"\/collections\/geissele-automatics\"\u003eGeissele Automatics\u003c\/a\u003e.\u003c\/p\u003e","brand":"Geissele Automatics","offers":[{"title":"Default Title","offer_id":60873781936462,"sku":"05-101","price":279.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/files\/geissele-ssa-trigger-ar-15-1.jpg?v=1789880986","url":"https:\/\/onyxarmaments.co.uk\/products\/geissele-ssa-trigger-ar-15","provider":"Onyx Armaments","version":"1.0","type":"link"}
