KWA Full Metal KM4 SR10 / M4 Airsoft AEG (2GX 9mm Gearbox Version)

"awesome gun, had it for about 6 months now. not a single problem so far. very accurate and can take a hell of a beating.

"LOVE THIS GUN
In my time playing Airsoft I have had many guns. But this is by far the greatest gun i have owned. The range and accuracy are superb along with the rate of fire. The ONLY con is the rail it can get a bit front heavy
5/5 should buy

"If you are considering buying this gun, I highly recommend you go for it! this gun is by far the best rifle I have ever owned. I have had it for well over 2 years and still no problems with it. Also, if you are looking for a realistic weapon, again this is it. the weight and feel just fits that realistic category. the only thing I wish that KWA would add to it is a bolt catch. love KWA. Has always been my favorite brand.

Pros-

heavy (could also be a con)
accurate
capable of running LiPo
solid construction (metal)
a lot of room for attachments
Looks awesome


Cons-
hmmmm...nope

"Even I, a diehard pistol shooter, have my own M4; it is a necessary piece of equipment for any and every player. I tend to keep this model handy in a rifle sheath, just in case the odds are stacked against my team and we need more firepower. I'm often found wielding this with one hand when we run into trouble.

It also holds its own as a DMR or sniper rifle, and can reach a target at 150 feet with ease. My SR10 is also outfitted with a powerful flashlight and a red dot sight, in addition to a 120-round polymer mid-cap magazine.

Since AEGs are not my strong suit, I haven't tampered with my SR10's internals. That isn't much of a problem, though, since the gun fires at roughly 390 fps with a 9.6v 1600 mAh battery and .20g BBs.

This assault rifle has seen the worst of the worst, the ugliest possible situations: Dense forest, high humidity, rain, intense heat and cold. Not a single piece of this gun has been damaged since I bought it back in October of 2011. Of course, there is the usual worn finish, but aside from that, this gun is built like a tank. Expect a long life of distinguished service from this reputable KWA product.

Pros:
- High muzzle velocity and rate of fire
- Long range (Accurate at well over 100 feet in the hands of a good marksman)
- Ample space for a 9.6v battery, which is to be expected from an M4.
- High-performance 2GX gearbox
- Bountiful rail space; can add anything, from grenade launchers to PEQ boxes.

Cons:
- Hard to say which mags fit with it. Be careful when choosing your spare mags.

Overall, this versatile gun is a must for any player's airsoft gun stockpile. For best results, add a KWA M93R to your loadout. Although it is a gas pistol, it is built with the same quality as the SR10, and proves to be a trustworthy sidearm should the impossible happen to this great AEG.

"I am an airsoft tech and have worked on a few of these and they are amazing! I have never worked on a higher quality gun. One of my clients has significantly upgraded his for a long range sniper rifle and as such has replaced a few things such as the inner barrel (to a 650mm 6.03) and the hop-up (to a r-hop). This AEG is well worth the money and with a little customization you can use it for anything from CQB to sniper to support weapon. I highly recommend replacing the stock hop-up unit (or at least the bucking) as it wears out quickly and has preformance issues.

Pros:
Can be modified to fit any role/play style
5 star internals (less the hop-up unit but thats an easy fix)
Amazing overall performance, especially accuracy and range
ROF (not too high but defidentaly not too low)

Cons:
Initial FPS (300 w/M90) so a M110 or M120 spring upgrade is highly recommended
Hop-up unit performance is a little shaky, I would recommend an upgrade

"I love this gun, I have had for some time and it's performance is near flawless.
Pros:
High quality gearbox
scale to real steal is almost perfect
accepts almost all M4 type mags
sound of gearbox is quiet and smooth
battery storage is great for a crane stock

Cons:
G2X Hopup needs to be worked on before it performs as well as the rest of the gun
some parts can only be swapped out with KWA parts

"I recieved this gun a couple days ago and I LOVE IT.

Pros
-Fantastic polymer and metal construction
- Extremely accurate

Cons
- Does NOT come with a battery

"The KWA Sr10 is an great preforming gun, and its worth the money.

-Shoots Hard (400 FPS)

-2GX gearbox
-Great Packaging

Cons:

Feeds every mag I have tried even jg/CYMA high caps
