The second-generation KWA airsoft rifles feature over 30 structural improvements and performance upgrades, making them the top choice for professionals and serious enthusiasts.

The KM4 RIS is the top choice for tactical and law enforcement trainers. It is dependable, well balanced, and fast handling.

Structural reinforcement has been engineered into the shell strengthening the overall integrity of the gearbox especially in areas prone to failure. The 2GX comes standard with six 9mm Spherical Bearings and Heat-Treated Precision Gear Sets offering flawless performance in all conditions.

Accuracy of the rifles has been greatly enhanced with the introduction of the 2G High Performance Bucking.

"Overall this gun performs absolutely amazing. I installed a TBB barrel, a raptor's full metal teeth piston and currently a matrix irregular pitch M120 spring. With an 11.1 lipo my ROF is 22-24 bps even with the stronger spring. I am easily engaging people at 75-80 yards, way outside of their range.

FPS (even before upgrades)
Full metal
Top notch internals

Heavy after awhile
Occasionally misfeeds
