The really short M4 KR series gun with Keymod rail system. A CQB monster of an airsoft gun.

The KeyMod universal interface system is a new innovation in the firearm industry used for weapon ergonomics and mounting tactical accessories. The KeyMod design was developed by VLTOR Weapons Systems and was open to the public domain by Noveske Rifleworks for all manufacturers to use.

KWA recognizes the benefits of this new design which allows for a wide range of accessory flexibility and weight reduction when compared to traditional quad rail systems and are proud to announce the KR KeyMod Weapons Platform. The KR series have been produced in several different lengths to accomodate a variety of needs.

The internals have been factory upgraded with a reinforced mechbox, hardened steel gears, high tension spring, high density piston, and Hi-torque/ Hi-speed motor. Because of all the reinforcement, KWA rifles are able to handle up to an 11.1v Li-Po battery, however a MOSFET is still suggested for safer operation. The rifle comes with a KWA 120 round mid-capacity magazine and there are plenty of replacements available. The battery compartment is located inside the crane stock of the rifle and can be difficult to install the first couple of times. First pinch the two tabs located directly underneath the stock plate and remove the plate. Slide the cells into the appropriate tubes making sure that the wires are correctly oriented and not in any pinch points. Once everything is properly positioned, close it back up and youre ready to go. Airsoft players love this rifle for its incredible "out-of-box" performance and great durability!
