The KWA KM4A1 Carbine has been discontinued, and has been replaced by the more affordable KWA CQR MOD.1. For those looking for a replacement premium grade AEG, there is the newly discounted KWA KM4 RIS Airsoft Gun.

The KWA KM4A1 Airsoft Carbine is the first production AEG engineered specifically for the unparalleled performance of today’s advanced battery technology – Lithium Polymer (LiPo). LiPo batteries provide higher capacity and superior performance surpassing the more common Nickel Metal Hydride (NiMh) airsoft batteries. However, this powerful battery requires the highest quality of internal components. To handle the extra power of LiPo batteries, the KM4A1 airsoft rifle is equipped with a reinforced metal gearbox utilizing KWA’s exclusive 8 and 9 mm ball bearing bushing combination and case hardened, precision metal gear sets. Heavy duty springs and high-torque motors are matched for optimum results. High-grade metal alloy are used for the production of the upper and lower receivers. The KWA KM4A1 Carbine was engineered to outperform the competition, offering ultra high performance and dependability straight out of the box!

KWA´s newest AEGs for 2009 feature the upgraded 2G gearbox and hop-up unit and bucking.  The new reinforced gearbox features larger 9mm bearings, while the 2G bucking enhances accuracy and aftermarket compatibility.

KWA KM4A1 Airsoft Gun Features:

-Full Metal Construction
-Length Retracted: 775mm
-Length Extended 857mm
-Adjustable Hop Up

KWA Automatic Electric Airsoft Guns, or AEGs, run on KWA's famed 2GX gearbox. This reinforced V2 gearbox houses 9mm ball bearings, hardened steel gears, and a bearing spring guide and aluminum piston head. The 2GX gearbox is known for performance and reliability, putting out over 20 rounds per second on a lipo battery. Each KWA AEG replica is constructed with realism and attention to detail.
