This KM4A1 by KWA airsoft rifle features over 30 structural improvements and performance upgrades that make it the premier choice for serious airsoft enthusiasts and professionals.

This gun is engineered specifically for the Lithium Polymer (LiPo) batteries and offers higher capacity and superior performance than the NiMh battery powered guns. But - this powerful battery requires internal components of the highest quality. To compensate for the extreme power of this advanced battery, the KM4A1 features a reinforced metal gearbox that uses KWA's case hardened, precision metal gear sets. A heavy duty spring and high-torque motor are incorporated for superior results.

The KM4A1 by KWA is a fully automatic electric gun that resembles many of the same aesthetic features of the original AR15 style rifle. This strong, robust rifle features a full metal alloy upper and lower receiver. The removable carry handle allows the user to attach various accessories. A 6-position stock provides the most comfortable shooting position. The proven 2GX gearbox and enhanced 2G hop-up bucking, give the KM4A1 reliability in the field, and extreme performance for those seeking a mission ready combat rifle.

Verified Purchase

Things I liked: seriously, everything amazing I got 15% off mine during Christmas best $170 I ever spent.extremely well built,if you are looking to get into Airsoft this gun is an extremely good base rifle.

Things I would have changed: nothing

What others should know: I said nothing but, I could not leave well enough alone and I now have a beast. I have done several upgrades since I've purchased this rifle.sub 2 in groups with .32 bb at 75 ft will punch and puts BB in aluminum can at same distance one side it has a 200-foot range with .25 BB paper plate size Target.I just turned 50 this year could not afford a sports car this is my midlife crisis extremely freaking fun stress relief,you will not regret your purchase if you choose to buy this rifle

  • David from USA asked:

    Are these rifles supposed to come with batteries? I just ordered 4 and am very thankful I ordered 4 batteries and 4 chargers....hoping to have a set of spare batteries.
