The pull follows the SSA's profile — smooth first-stage take-up into a crisp, reliable second-stage break — manufactured with streamlined production to reach a price point, not by cutting the metallurgy or the safety margin that make Geissele triggers trustworthy.\u003c\/p\u003e\u003cp\u003eFor a first trigger upgrade, the G2S is transformative: mushy, gritty factory pulls become a clean two-stage you can actually shoot to the rifle's potential.

It will not fit large-pin receivers — confirm your pin size before ordering. Installation is armourer-level work; carry out full function and safety checks after fitting and before live fire.\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\u003e05-145\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eYour first Geissele — and a proper one. \u003cstrong\u003eOrder the G2S 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":60873782001998,"sku":"05-145","price":195.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/files\/geissele-g2s-two-stage-trigger-1.jpg?v=1789880987","url":"https:\/\/onyxarmaments.co.uk\/products\/geissele-g2s-two-stage-trigger","provider":"Onyx Armaments","version":"1.0","type":"link"}
