Knight’s Armament URX 3.1 Rail, 13.5″
KAC PN 30325
The KAC URX 3.1 Rail is a free floating, fully modular replacement forend for the AR-15 platform. 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. Add-on KAC URX 3.1 Rail Panels and additional rail sections allow shooters to customize the forend to their needs (both sold separately).
For use on AR-15/SR-15 based platforms only. Installation instructions, barrel nut and hardware are included. Barrel nut wrench sold separately.
