"I have this gun for about a year and man does it run like a champ!

I put a 9.6v battery on it and it shoots really fast! All metal body, great gearbox, fuse, sturdy stock and buffer tube, easy to upgrade.
I recommend this gun to all airsofters.

"This gun is the best gun I have ever owned. This thing kills my sr-12 and my ak-47. This gun is ready for field and cqb right out of the box. It is also lipo ready. It has a 14 negative thread for any silencers you want to put on, but the flash hider is very hard to get off. It has a full metal top and bottom receiver.

"Amazing Gun Easily a 5 star for me.

balanced weight
flawless feeding magazines
usage with an 11.1 lipo is fine with this gun
high rof
Fps around 400 with .2
accurate with .25s
Takes a beating

Although the weight is balanced around the gun it still is on the heavy side
Extremely picky with mags

KWA Full Metal KM4A1 Airsoft AEG Rifle - (Rifle)

The second-generation KWA airsoft rifles feature over 30 structural improvements and performance upgrades, making them the top choice for professionals and serious enthusiasts.

The KWA KM4A1 Carbine is the first production AEG engineered specifically for the unparalleled performance of todays 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!
