The KWA KM4A1 Carbine was the first production AEG engineered specifically for the unparalleled performance of todayâ€™s advanced battery technology â€“ Lithium Polymer (LiPo). LiPo batteries provide higher capacity and superior performance surpassing the more common Nickel Metal Hydride (NiMh) batteries. However, this powerful battery requires the highest quality of internal components. To handle the extra power of LiPo batteries, the KM4A1 is equipped with a reinforced metal gearbox utilizing KWAâ€™s unique 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!
