The AR15 was originally designed as part of the U.S. militarys initiative to develop a lighter smaller caliber weapon as the standard infantry rifle. This innovative weapon utilized aircraft technology to lighten the rifles overall weight.  This led to the creation of the M16 which has served as the backbone of the U.S. Military for more than 40 years.  Since its inception shorter variations of the M16 were developed for the US Special Forces and other branches of the military, such as the M4A1.

The KM4A1 by KWA is a fully automatic electric gun that follows many of the same aesthetic features of the original AR15 style rifles.  Full metal alloy receivers ensure that the weapon is strong and robust.  A flat top receiver allows the user to attach an optic or utilize the included carry handle for easy transport. Updated with the proven 2GX gearbox, the KM4A1 is ready for outdoor combat in almost any environment.  The KM4A1 brings KWAs quality and strength for those seeking an excellent basic combat rifle.

3 of 5 Gun Assoc. purchase November 29, 2011
Reviewer: Dewey Maroney from Renton, WA United States  
Fast shipping and arrived perfect. However purchased the battery you recommended on another purchase and it dd not fit the gun. You should not recommend additional purchases that won't work in the gun. Disappointed.

5 of 5 GREAT GUN July 28, 2009
Reviewer: Robert Cooper from HI United States  
solid feel through the gun. no wobbles through the collapsable stock. very good accuracy. ROF is very good. had it for 6 months and still running great. though battery sucks to put in. its no big deal. also sucks batteries fast through games. get at least 2 mini type. my begining fps was 410 but subsided to 389 over 2 1/2 mags of ammo (500 high caps).
