KAC Knights Armament URX 4 5.56 M-LOK Forend Rail Kit – 10.75″

Out of stock

$302.12

Knights Armament Co.’s URX 4 10.75″ M-LOK Forend Assembly Kit is a fully modular design that utilizes the revolutionary M-LOK accessory mounting system.

M-LOK accessories may be mounted anywhere along the URX 4’s length making it one of the most user-configurable designs on the market.

Length: 10.75″
