Unlike traditional quad rail designs\" the URX 3.1 incorporates short sections of M1913 Picatinny rail at its front and rear ends for mounting tactical accessories\" eliminating the commonly unused sections of rail for reduced overall weight and a more comfortable grip. A total of 4 integral  QD sling swivel sockets are provided for ambidextrous sling compatibility. This URX 3.1 rail requires that the rifle have a carbine or mid length gas system and a low profile gas block. Disassembly of the rifle's gas system and removal of the factory barrel nut will be necessary. This forend uses a proprietary barrel nut that MUST be installed using a KAC URX Barrel Nut Wrench (not included). For AR-15\/SR-15 based platforms only; not compatible with SR-25 variants. Installation instructions\" barrel nut and hardware are included.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures\u003c\/b\u003e :\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eUpper receiver rail extending adapter system\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":29354436657212,"sku":"KNAC30590","price":301.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0259\/8459\/8076\/products\/RPLKNAC30590.jpg?v=1564213933","url":"https:\/\/rsr-latest-2round-qafri-jul-26-16-01-41-ist-2019.myshopify.com\/products\/kac-urx-3-1-forend-assy-556-10-75","provider":"rsr-LATEST-2ROUND-QAFri Jul 26 16:01:41 IST 2019","version":"1.0","type":"link"}
