The KAC Medium URX II free floating forend features an integral, flip-up front sight assembly that folds flush with the continuous top rail when not in use, creating a seamless look. Full length mil-spec M1913 Picatinny rails are located at the 3-, 6-, and 9 o’clock positions, making the URX II compatible with any number of rail-mounted tactical accessories. Includes three KAC 11 Rib Rail Panels.
Rifle Requirements: This URX II 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 (PN: 20495, Sold Separately). For AR-15/SR-15 based platforms only; not compatible with SR-25 variants. Installation instructions, barrel nut and hardware are included.
