{"product_id":"kac-m4-carb-rail-adapter-system-556","title":"Kac M4 Carb Rail Adapter System 556","description":"Knights Armament Co.'s M4 RAS 6.25\" (Rail Adapter System) was developed for use on the US military's M4 Carbine\" and with over 1 million rails issued to date\" it is one of the most battle proven designs available for the AR-15 platform. This non-free float handguard is a simple-to-install\" drop-in upgrade that features genuine Mil-Spec M1913 Picatinny Rails along its entire length. What sets the M4 RAS apart from other 2-piece quad rails on the market is that it securely locks to the rifle's barrel nut via a clamp and screw arrangement\" making it a very solid foundation upon which to mount tactical accessories. Includes three KAC 11 Rib Rail Panels. The M4 RAS is a drop-in replacement part for standard\" 2-piece polymer\" M4-type handguards. The rifle must have a carbine length gas system\" delta ring assembly\" fixed front sight\/gas block\" and round handguard end cap. Lighter barrel profiles work best (M4 or Government contours). Heavier barrel contours may require modification to the inside of the rail. For AR-15\/SR-15 based platforms only; not compatible with SR-25 variants. Installation instructions are included. Aluminum black finish.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures\u003c\/b\u003e :\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eIncludes three KAC 11 Rib Rail Panels\u003c\/li\u003e\n\u003cli\u003eFor AR-15\/SR-15 based platforms only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Knights Armament Company","offers":[{"title":"Default Title","offer_id":29349865750588,"sku":"KNAC98064","price":250.73,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0259\/8459\/8076\/products\/RPLKNAC98064.jpg?v=1564195204","url":"https:\/\/rsr-latest-2round-qafri-jul-26-16-01-41-ist-2019.myshopify.com\/products\/kac-m4-carb-rail-adapter-system-556","provider":"rsr-LATEST-2ROUND-QAFri Jul 26 16:01:41 IST 2019","version":"1.0","type":"link"}
