It replaces a standard collapsible stock on the existing tube, so no change of buffer or spring is normally involved. Commercial-diameter tubes are not compatible, so confirm your tube specification first. Set cheek height and pad position at the bench behind your optic; the locks hold your numbers.\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 carbine receiver extension\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eCollapsible precision stock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eBlack, Flat Dark Earth, Coyote Brown, Olive Drab Green\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003eMedium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAdjustment\u003c\/th\u003e\n\u003ctd\u003ePrecision cheek riser \u0026amp; buttpad\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eB5 Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003eCPS-1304 · CPS-1305 · CPS-1306 · CPS-1308\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eFit, dialled. \u003cstrong\u003eOrder the CPS Medium 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 \u003ca href=\"\/collections\/rifle-shotgun-stocks\"\u003eRifle \u0026amp; Shotgun Stocks\u003c\/a\u003e, \u003ca href=\"\/collections\/precision-rifle-stocks\"\u003ePrecision Rifle Stocks\u003c\/a\u003e, \u003ca href=\"\/collections\/ar-15-parts-accessories\"\u003eAR-15 Parts\u003c\/a\u003e or browse all \u003ca href=\"\/collections\/b5-systems\"\u003eB5 Systems\u003c\/a\u003e.\u003c\/p\u003e","brand":"B5 Systems","offers":[{"title":"Black","offer_id":60873784721742,"sku":"CPS-1304","price":269.99,"currency_code":"GBP","in_stock":true},{"title":"Flat Dark Earth","offer_id":60873784754510,"sku":"CPS-1305","price":269.99,"currency_code":"GBP","in_stock":true},{"title":"Coyote Brown","offer_id":60873784787278,"sku":"CPS-1306","price":269.99,"currency_code":"GBP","in_stock":true},{"title":"Olive Drab Green","offer_id":60873784820046,"sku":"CPS-1308","price":269.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/files\/b5-systems-collapsible-precision-stock-medium-length-1.webp?v=1789881011","url":"https:\/\/onyxarmaments.co.uk\/products\/b5-systems-collapsible-precision-stock-medium-length","provider":"Onyx Armaments","version":"1.0","type":"link"}
