"I bought this gun 2 years ago with amazing expectations. Before I was using a stock g&g combat machine on an 11.1 lipo and I was really just looking for a more reliable gun that I could upgrade later. Probably 6 months after buying the gun I began my extensive internal upgrades. I built an insanely fast gun that used a massive brick battery. From there I switched the internals to a new gearbox and new gun and threw a Polarstar jack and just recently put in a protech. I've now added an R-hop and a 6.03 tightbore. Although I only used this gun "stock" for 6 months or so but I was more than happy with it. The FPS and rare of fire were great with an 11.1. I never worried about anything breaking or anything of that sort. My only con with this gun is the 2 piece hop up. I really wish I could use a prowin or a retro arms hop up.

"This gun is amazing. I am kinda new to airsoft ( played for 2 years and plan on playing forever lol). This was my starter gun and at the time I didn't know much about airsoft guns and was kinda let down cuz I wanted an m249 but I took this gun anyway. Once I started to use it on the field and got to know more about airsoft guns internal wise I learned that an m249 is nothing compared to this sr7. Everything about this gun is perfect and worth it.


Amazing stock internals

I think it's made of steel

Pretty light weight for a steel gun

Comes with mag (kwa 120)

Too accurate to be true. Even with the fairly short inner barrel. I was able to be shot at multiple times then just turn around and shoot once and the other team would get mad cuz they thought I was cheating but the sr7 is just too accurate for CQB lol.


I couldn't buy 10 at once

The front sling mount makes a lot of noise but you can just tape it down and there will be no noise

2 piece hop up unit (this can be a pro or a con, personally I see this as a con cuz I can't put another hop up in it unless it's another kwa)

Doesn't come with battery or charger (most guns don't anyway)

"First off, this is one of the best performing stock rifles I've owned and I loved it. It performs great especially for a stock rifle.

Great performance right out of the box
High ROF
FPS is under most normally field limits

The new 2GX gearbox -_- This makes it extremely hard to upgrade but if you don't want to upgrade this is the perfect rifle for you.

"This gun is great if you never take out a body pin, the second you touch anything on the inside your done for. the 2 piece hop up sucks. the rof is pretty bad. the fps is perfect for pretty much everything besides dmr, which this gun obviously isnt for. I would not reccomend this gun. If i were you looking for a gun I would go grab a G&p m4. the wiring also sucks in this.

"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.
