Questions & Answers

Product Info for Knight's Armament URX III Forend Assembly

The KAC URX III Rail is a free floating, fully modular replacement forend for the AR-15 platform. Unlike traditional quad rail designs, the URX III incorporates short sections of M1913 Picatinny rail at its front end for mounting accessories, eliminating the commonly unused sections of rail for reduced overall weight and a more comfortable grip. A QD sling swivel socket is provided on each side at the rear of the rail 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).image
