Out of stock



The KAC URX 3.1 Modular Rail Handguard is fully licensed by Knight's Armament Airsoft, and designed specifically for airsoft use in milsim and training. The URX 3.1 replica airsoft rails are made from aircraft grade aluminum with an anodized finish. Like the real URX 3.1 handguards, these feature an uniterrupted upper rail for optics and sights, and feature hard-mount picatinny sections at the front of the handguard for stable light or laser aiming mounts. The handguard features two rear QD sling swivel sockets, one on each side, and three at the front: one on each side and one at the six o'clock positon.

The Knight's Airsoft URX 3.1 13.5 Inch Handguard is the ideal length for use on M4s with 14.5 inch barrels. It can also be equipped on standard 16 carbines with the 20 inch barrel, as long as the front sight post is removed. The threaded ports on the URX handguards allow for attachment of grip panels, hand stops, and other modular grip options. The longer 13.5 inch URX adds rail slots at the back of the handguard for additional mounting options.

KAC URX 3.1 13.5 Inch Airsoft Modular Handguard Features:

-Fully Licensed by Knight's Armament Airsoft
-Improved Rail System Design
-Aircraft Aluminum Construction
-Uninterrupted Upper Rail
-Shorter Forward Rail Sections for hard-mounts
-5 QD Sling Swivel Sockets
-Free Float Design
