B&T sets a new standard for rifle suppressors with the RBS (Reduced Back Pressure) .223/5.56. This innovative suppressor features a unique “flow-thru”, low-pressure chamber design to absorb a considerable amount of the expanding gasses – this results in a significant reduction (and in some cases the elimination) of excess gas pressure exiting the weapon’s ejection port and charging handle locations. The vast reduction of gasses makes the RBS Suppressors an ideal choice for firearms intended for high volumes of fire such as assault rifles, PDW’s, and semiautomatic rifles. Another benefit of the RBS design is reduced carbon fouling, as well as less gasses being redirected at the operator’s face allowing them to see and breathe easier. Like all of B&T’s premium suppressors, the RBS Rifle Suppressors greatly mitigates the level of sound and flash signature generated during firing. In addition, these particular RBS Suppressors are outfitted with Quick Disconnect mount for fast and easy attachment/removal.

The KAC Keymod Flat Panel Kit includes a set of seven 5.5 polymer rail panels. Each textured panel snaps securely to any bare section of Keymod equipped rail, providing a more positive gripping surface and also insulating the support hand from barrel heat. These rail panels are very thin adding almost no width to the handguard. While designed for the URX 4 rail, these panels will also fit any other rifle handguard that has a Keymod interface.

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 Knights 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. The 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, Knights Armament Company demonstrates its continuing determination to intelligently design effective products.
Two QD sling swivel sockets built in at the rear of the rail. Includes shim kit and installation wrench.
The KAC URX 4 Rail is a fully modular design that utilizes the revolutionary KeyMod accessory mounting system. The URX 4 Rail is stronger and more stable than previous URX designs due to its one piece construction. It is also lighter due to its Integral Barrel Nut (IBN) system of attachment. The IBN system allows the rail itself to act as the barrel nut when torqued onto the rifle, completely eliminating the need for a separate steel barrel nut. KeyMod accessories may be mounted anywhere along the URX 4s length, making it one of the most user configurable designs on the market. The URX 4 includes two QD sling swivel sockets, one on the left side and one on the right.
Specifications:
Length: 10.75″
Weight: 10.2 oz
Inside Diameter: 1.55″
Outside Diameter: 1.68″ (Side to Side)
Each URX 4 Rail comes complete with an installation wrench, shim kit and instructions. Other lengths available include 8.5″, 10″, 13″, and 14.5″.
