KWA M4A1, built for lipoly


The KWA KM4A1 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) 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 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!

* Results are based on tests conducted with 11.1v 1500mAh LiPo batteries. Individual test results may vary depending on brand and specs of power source, bbs, and chronograph used.
