The AR15 was originally designed as part of the U.S. military’s initiative to develop a lightweight and smaller caliber weapon as the standard infantry rifle. This innovative weapon utilized aircraft technology to lighten the rifle’s overall weight. This led to the creation of the M16, which has served as the backbone of the U.S. Military for more than 40 years.

The KWA RM4A1 ERG is an AR style, Electric Recoil Gun [ERG] that utilizes the patented Kinetic Feedback System [KFS]. This gives the user felt recoil with every trigger pull. All ERG Series rifles feature a mechanical/electrical cut-off system that works in conjunction with the ERG magazines to feed every BB and stop firing when the magazine is empty. Highlighted features of the RM4A1 ERG are metal alloy receivers, MilSpec buffer tube and stock, a flat top rail, which allows operators to customize their weapon configuration, and an operational bolt catch feature that provides the user with unparalleled realism by mimicking fundamental AR15 weapon manipulation. Similar to real AR15 style rifles the RM4A1 ERG’s modular design allows limitless customization options to best suit the individual’s training and MilSim needs.
