"An Absolutely amazing gun! I just got mine a week ago and this past weekend I put 3000 rounds through it in 2 days. I did not have a single issue with it. The orange tip easily unscrews but first you have to remove a very tine screw in the bottom of the flash hider before you can unscrew it. Everything about the gun is very solid and the gun has a great rof even with a 9.6v 1600mah butterfly battery. I use .25g bbs in it and this gun is crazy accurate. Some will say to put in a tighter barrel in this gun, but personally i'd advise against it. I was able to hit very small targets with great consistency. I was also able to shoot the gun up to 150 feet with the gun which is probably more than I'll really get a chance to use. Getting that distance with such a compact gun is great too since you have the advantage of the cqb size gun with the range of longer guns. I used the kwa k120 mags (it comes with one unlike shown in the picture), and the did not jam up after all the rounds I shot.

"I have owned mine for quite some time and i really love it. The KWA KM4 SR7 is a great full metal gun for intermediate players to advanced players. Here are the pros and cons:

-Great for CQB
-Full metal
-Good for upgrades
-Has KWA bucking
-7" rail system
-fits most batteries

-Some parts are proprietary so make sure you want it
-Hop up is 310-350 fps. The sweet spot is 335 fps
-You might need to re-thread it if u want a new rail system
-It's heavy, so for you young players I would get a g&g combat machine. Just highlight it and search it here on

Upgrades I've done:
-M120 spring
-6.01 Madbull tight bore barrel
I also removed the front sight and but a g&p gas block, you're going to need it for the KWA rail system.
-Magpul angled fore grip
-Magpul rail covers
and a Magpul pts stock.
it shoots 410-430 fps*

The BB weight I recommend for the stock gun is .25 bbs by Elite Force. You never can go wrong with Elite Force.

So over all its a 5 out of 5

"i absolutely love this gun. I have used it in a couple of cqb games and it preformed is very easy to customize besides for the fixed front sight. i have put a magpul angled fore grip (also recommended) that maked the gun look so bad ass. the only con was that i felt that the hop up doesnt do much but i still love the gun and highly recommend it for cqb

"No... Just no... i have no idea what KWA was thinking when they put in that HORRIBLE spiral cord to connect to the battery... Plus to polish that mistake they shove a external fuse in our face. Both of these make the stock pretty much un-upgradable. Otherwise this gun is GREAT. i love it with all my heart im upgrading most of the externals EXCEPT THE STOCK BECAUSE THAT IS IMPOSSIBLE... so yea :D

Shoots GREAT
nice weight
High FPS
Nice Range for a CQB

Stock is horrible
spiral cord
external fuse
Non removable front iron sight
Front sling mount clip flops around making a loud ting noise...

"Love this gun, 4 stars because the externals are just about G&G quality. If you are like me and are deciding for your first airsoft gun, it seems that G&G and G&P are a better choice, but let me tell you that KWA makes quality weapons that will be way more reliable and better than any other brand (unless its systema or TM).

$60 gift (I recommend using it for the K120 mags 6 pack)
Very well built
K120 Mags are amazing.

Heavy (I'm 13, so its not that bad but definitely not something for anyone younger.)
The groupings can vary, pop in a g&g green bucking and the bb's will soar.

"I drove up to the evoke super store to get this gun. Walking in not knowing what kind of gun I wanted I was leaning for m4 models because I always like them. so the guy asked me what was looking for I told him I want something all metal durable and under 400 fps around 370 would be great. so you can go outdoor or indoor.

-Good fps 350-370
-Good Rate of Fire
-Full Metal
-(got 6 mid cap mags for free due to special going on)
-(9.6v battery with package)
-Rails for anything and everything
-KWA Hop-Up Bucking has two teeth for better accuracy
-Extremely accurate

-could be heavy for some players

other then that probably one of the best guns i have ever purchased.
If your looking for a gun its a bit pricey but worth every penny!

"I have owned this rifle for about 4 months now so I feel like I can give a solid review about it.

This rifle is hands down the best gun I have ever owned.

Pros -

Insane Accuracy
Solid Trigger Response
Metal Upper and Lower Receiver
Retractable Crane Stock
Heavy In Weight (about 8 pounds)
7" Picantinny Rail System
Metal Sling Mount
Spacious Battery Compartment in the Stock
Solid Selector Switch
Great Motor Grip
High RoF
Easy to Take Apart/Reassemble

Cons -

Somewhat Wobbly Stock
Selector Switch Will Come Loose After a While (tightened with 0.05mm allen key)

Other than that, this gun is outstanding and it is worth every penny. Also, if you buy the gun, Evike will give you $60 for free! I bought myself a vest with it :)

I replaced my inner barrel with a KM Head 1950 series 395mm 6.02mm inner barrel and it was well worth the upgrade. It now shoots a little over 200ft with .25 gram bb's :) One thing you should pay attention to, NEVER clean your barrel with silicon oil. It will end up swelling your bucking and decreasing the gun's performance. I had to replace my bucking with a new one because I realized my mistake. You can read how to properly clean your KWA rifle on the KWA forums.

I highly recommend this gun and you will not regret your purchase.

"Hands down the best airsoft gun I have ever owned. This thing is a monster! I love the way it sounds with the 11.1v Li-Poly battery.


- Very Accurate
- Reliable
- Rugged
- Great RoF
- Sounds awesome
- Lots of rails for attachments
- Full Metal construction makes it handle like a real M4
- KWA Hop-Up Bucking has two teeth for better accuracy and backspin


- Battery compartment is very tight with my 11.1v 1800mA Li-Poly battery
- Can't be converted to ambidextrous operation (I'm ambidextrous.)


Amazing gun. If you're serious about airsoft, this is a great choice.

I highly recommend getting the 6-pack of KWA K120 mid-cap mags as your free gift. They feed great, give the experience of reloading, and fit the $59.99 free gift. They also don't rattle like high-caps, so you can be really sneaky.

"This gun is absolutely awesome, it has some great weight to it and it's made by KWA, one of the best airsoft companies around. The 2GX gearbox is great and has yet to fail me, the kwa K120 midcap that the gun comes with is really good, it feeds perfectly and it's so good that I bought 6 more. I have to say that this gun is one of the best AEG's I've ever owned and it's definitely worth every penny I spent on it.

Full metal
Great ROF
Li-po Ready
Under 350 FPS

The full metal receiver can be a bit heavy in cqb

Other than that, I strongly recommend you buy this gun.
