KAC URX 4 IBN Keymod Rail 5.56mm 14.5″ Length
URX 4 The URX 4 is a continuous top-rail system that utilizes the Keymod mounting brackets developed by Vltor and Noveske. This rail system is built stronger and more stable than previous designs due to the absence of a removable bottom rail. The modular layout allows an end user to fully customize exactly where to place accessories without the use of specialized tools, small parts, or additional forces applied to the barrel. The URX 4 is currently available for 5.56 rifles in 8.5″, 10″, 10.75″, 13″, and 14.5″ lengths, and is equipped with Knight’s unique IBN mounting configuration. The idea was to create a more modular, and thus more serviceable, rail system that still maintains its strength and stiffness. Th IBN system torques the rail onto the weapon and allows the rail to act as the barrel nut.
This design was developed to increase stabilization and provide a simpler solution that requires less specialized tools to install and maintain. A full array of modular accessories, iron sights, and panel kits utilizing the Keymod mounting brackets have been developed specifically to accompany this rail system. With the introduction of the URX 4, Knight’s Armament Company demonstrates its continuing determination to intelligently design effective products. It is not suggested to use this rail with a 14.5″ or shorter barrel unless using a muzzle device such as the AAC flash hider which can be installed from the end with a tool.

Surefire Warden Fast-Attach® Blast Regulator
Non-NFA device directs blast concussion away from areas left and right of shooter’s firing position
Precision-machined of rugged stainless steel, heat treated and coated with a durable Cerakote™ finish
SureFire SOCOM Fast-Attach® adapter mount provides fast, easy attachment and removal
Blast Forward. The SureFire Warden Blast Regulator for 5.56 and 7.62 mm weapons is engineered to direct the concussive blast of the fired round forward of the weapon system without venting gas to the side, as seen with standard muzzle brakes. This aids in reducing the overpressure felt by others immediately to the left and/or right of the shooter’s firing position. It also limits any dust signature from the weapon when fired from a prone position. This version of the Warden quickly and easily mounts to any SureFire SOCOM Fast-Attach® 5.56 or 7.62 muzzle device through the same patented system found on SureFire SOCOM Fast-Attach® Series suppressors. Unlike sound suppressors, Wardens are not NFA devices and are available wherever SureFire products are sold, without any of the restrictions associated with suppressors. -

$294.76M4 Carbine RAS, 5.56mm, with three 11-rib panels The KAC M4 RAS (Rail Adapter System) was developed for use on the US military’s M4 Carbine, and with over 1 million rails issued to date, it is one of the most battle proven designs available for the AR-15 platform.

What sets the M4 RAS apart from other 2-piece quad rails on the market is that it securely locks to the rifle’s barrel nut via a clamp and screw arrangement, making it a very solid foundation upon which to mount tactical accessories. Includes three KAC 11 Rib Rail Panels. For other rib panel lengths and colors, click here Rifle Requirements: The M4 RAS is a drop-in replacement part for standard, 2-piece polymer, M4-type handguards.
