The friction-lock interface still clamps the stock firm against the receiver extension for a stable, repeatable cheek weld; the storage slims down to efficient battery tubes rather than full compartments.\u003c\/p\u003e\u003cp\u003eThe slimmer housing handles faster and clears kit more cleanly, while the rubber buttpad and reinforced polymer construction carry the usual Magpul guarantees.

Commercial-diameter tubes are slightly larger and will not take it, so check your tube specification before ordering — if you are not sure which you have, measure the tube or contact us with your rifle's make and model. Slide on, set length, engage the lock; battery tubes load from the rear.\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 carbine stock with battery storage tubes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eReinforced polymer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eBlack, Flat Dark Earth, Olive Drab Green\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAdjustment\u003c\/th\u003e\n\u003ctd\u003eFriction lock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMagpul Industries\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMPN\u003c\/th\u003e\n\u003ctd\u003eMAG378-BLK · MAG378-FDE · MAG378-ODG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003eThe lighter way to lock down. \u003cstrong\u003eOrder the ACS-L 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\/magpul-industries\"\u003eMagpul\u003c\/a\u003e.\u003c\/p\u003e","brand":"Magpul Industries","offers":[{"title":"Black","offer_id":60873787343182,"sku":"MAG378-BLK","price":105.0,"currency_code":"GBP","in_stock":true},{"title":"Flat Dark Earth","offer_id":60873787375950,"sku":"MAG378-FDE","price":105.0,"currency_code":"GBP","in_stock":true},{"title":"Olive Drab Green","offer_id":60873787408718,"sku":"MAG378-ODG","price":105.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1081\/3223\/7646\/files\/magpul-acs-l-carbine-ar-15-stock-mil-spec-mag378-black.jpg?v=1789881031","url":"https:\/\/onyxarmaments.co.uk\/products\/magpul-acs-l-carbine-ar-15-stock-mil-spec-mag378","provider":"Onyx Armaments","version":"1.0","type":"link"}
