KWA Full Metal KM4 SR5 Airsoft AEG (2GX 9mm gearbox Version)

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

With an overall length of 25" the SR5 is the perfect CQB weapon. Tuned for high speed, the SR5 fires at over 20 rounds per second yet maintains a velocity of 350 feet per second within the limits of most indoor arenas.

At the heart of every KM4/16 series rifle is KWA's Second Generation Extreme (2GX) gearbox, designed to resist cold temperature failures. Structural reinforcement has been engineered into the shell strengthening the overall integrity of the gearbox especially in areas prone to failure. The 2GX comes standard with six 9mm Spherical Bearings and Heat-Treated Precision Gear Sets offering flawless performance in all conditions.

Accuracy of the rifles has been greatly enhanced with the introduction of the 2G High Performance Bucking. The bucking utilizes a set of uniquely designed "Fins" that produce remarkable consistent performance shot after shot.

"This gun is amazing! shoots stupid fast. i reccomend a high cap cuz the mids run out way too fast. its sick accurate and for the size , has a good range. the price is sooooooo worth it, it will never fail you
KWAs are where its at
by Jonathan P. on 04/29/2010

I cant stress how well this thing is built. The accuracy is amazing. Even at 150 feet, with that short barrel, its consistent. The ROF is insane...about 18 rps on an 8.4!!! Thats right!!! Around 22-24 rps on a 9.6v. The externals are amazing. The machining quality is just as good as my REAL AR-15/M4

I haven't peeked at the internals yet, but the look of it from the outside....its promising. After all, this is one of the only truly LIPO ready rifles. (and you dont even need a lipo to have a great ROF!!!)

Accurate (even with the itty bitty barrel!)
SEXY externals
Internals are the best you can buy stock...
Compact and lightweight.
Versatile (you can use this rifle for both CQB and outdoors)

You kidding??? NONE BABY!!!

by Tom C. on 03/13/2010
"this gun is amazing. very sturdy and accurate considering the short barrel. you could probably only fit a 9.6v 1600mah or a small lipo in the crane stock.

pros: sturdy
all metal except for stock and pistol grip
nice internals

cons: the mags jam sometimes while trying to put them in the mag well

overall this gun is great for cqb. for the field you might want to get a bigger barrel or the SR10. awesome gun though
