"Hey guys im going to do a review on this gun. This is my first review ever on a gun but i just have to say this gun is amazing. I have had it possibly going on 2 weeks now and i have already played a game with it, and it just preformed amazing! This gun is worth the value. You get what you pay for. The crane stock does wobble a little bit, but nothing that you can really notice. The gun shoots hard, and fast. It is worth every penny!

"I've had this gun for about a year now and it has not had a single problem. The 20 RPS dominates in CQB, but its incredible range allows me to take accurate and powerful shots from across the map (100 yards). Mine usually chronographs at ~380 fps with a 9.6v nun-chuck battery. the full metal design makes it extremely durable. Zero maintenance or upgrades has been done on this gun and it is still one of the best on the field.

"I've had this AEG for almost a year now and all I can say is that its AMAZING. It hasn't failed me AT ALL so far.
Everything about it is sturdy and it has been manufactured excellently.
I use this at TAA airsoft and it outclasses every other gun there.

I would take this over a G&P or TM any day.

With KWA's excellent warranty and life-time tech service, this will never go out of service on you (Especially if you're comfortable with working with gearboxes.)

Buy this. It is definitely worth the money!

"This is my second KWA gun. My first is the SR10 and this year I got the SR7 for CQB game play. It turns out that this gun works best in both. It handles itself well in the field and got me the range that I needed. It also is make so durable now. the only think that I did not like was the missing hicap now. It comes with a KWA pmag style mid cap. It is nice but I would rather have more bbs. I have been using 11 v lipo on it and I get amazing ROF out of it. It is still stock at this time and great gun. KWA has done it again with an amazing gun.

"This gun is in my opinion the best indoor M4 money can buy. To start off KWA has never let me down and sure knocked it out of the park this time with this beauty! I bought this gun and went with it to my local indoor field (Patriot Airsoft) and in chrono with .2 gram BBs it shot a solid 346-350. In my experience this has never let me down shoots fast hits hard (for indoor) and is very small amazing for CQC play and just like always from KWA Full Metal which i love.

All metal (exept crane stock and grip)
shoots fast
perfect for indoor with .2
amazing feel you feel like you are holding something truly special

None so far!!

Overall its expensive but buy it its worth is i give this *****

I've had this gun for about a year now and haven't had any problems with it.
Its the most sturdy build of a M4 I've had. Also it looks sweet with a suppressor. Mine shoots 24 rps and about 380 fps. It shoots the same fps as an sr10 and 12 but at half the size.

"I got this about a year ago and all i have to say is that it was worth every penny. In fact i love it so much that i have but close to 500 extra dollars upgrading it. The only thing that i recommend is to upgrade all the internal parts like the pistons, gearbox and so on if you want to run a lipo battery. Also if you plan on buying a silencer you will have to shave down the tip because it is close to impossible to take off and buy a silencer that fits all guns.

Shoots hard
Full Metal
Great FPS
High rate of Fire
Great Motor

Some of the parts are very delicate inside so take it in to fix your gun don't do it yourself unless you know what your doing.

"I've had this gun since december and i love it its great for most fields runs about 390 witch is right under the max fps for most fields and can be used for indoor and outdoor fields!

everything about it
lipo ready
great rate of fire

don't buy from a store you will kill the motor within a half a full day game and u will want to put lock tight on the reciver bold and motor plate and ect. other than that its great!

must have!

"Great rifle, just got it today. Fielding it Sunday but I decided to fire off a few mags out my door. It has a slight feeding problem that I'm doing research on, but it only happens occasionally. It's a very very loud rifle, and a great kick behind each shot, you can feel the power behind it. The rifle is built so well, it feels like it's all metal (it is, actually, save the crane stock and handgrip, which kinda feel like metal anyway). My friend has the same exact rifle and dropped it out of a 3rd floor window onto concrete and not a scratch.

Great construction
Firepower you can just feel
Fluent full auto
Great range, perfect for field games as well

Slight feeding problem, something to do with the hop-up not being properly in place
Mag it comes with has to slide exactly up the magwell, otherwise it won't go in. I just find it annoying to reload on the go.

This gun will last you a lifetime and a half. Seriously buy it.

-Good Weight
-Metal parts that need to be metal, are in fact metal.
-Amazing range for the size.
-Looks different than any other M4/M16.
-Solid feel
-Great FPS (Most think under 400FPS is bad, but most stations only allow guns under 350)
-Sounds amazing
-A little kick when firing with a LiPo, makes it feel a lot more realistic.
-2GX allowing better control of the BB.
- 3 different center sling mounts. Great for right, and left handed players.

-The gun comes with an orange flash hider to meet US law, yet getting it off to fit a silencer may unthread your 14mm- thread. (Happened to me, not really a con, but just watch out.)
- The gun doesn't have a built-in microwave so I can eat lunch while in the game. (KWA needs to work on that)
-Seriously, there's nothing wrong with this gun.

Overall, this gun is well worth the price. It's speed, sound, and overall construction make this gun earn its 5/5 rating. KWA has outdone themselves again with this KM4 SR7. If you're looking for a gun, you've come to the right one on the right website.

"Ive had this gun for 5 months now and i am totally loving it. the trade marks are simply unbeatable, the mag it came with feeds flawlessly, and the fps and range is outstanding. the fps had a constant 365-370 fps right out of the box with a 9.6 nunchuck battery. the range goes atleast 150 yards. i sighted this gun in with my holo sight and i can hit a quarter from 30 yards. this gun is simply amazing and is well worth the money.

"I got this gun a few months and i love it. I recommend this for any veteran player or new person. If you dont plan on going to a park don't even bother buying a gun like this. Although i do recommend buying it online because i bought it at a store and the motor broke on me the first day.

realistic weight
all metal
great range
looks awesome
feels great
good fps
shoots straight

the mag jiggles a little
