"Excellent gun!!!!!! i recieved it broken, but i took it back and got it good as new :). i used .25s during a battle, i say it shot at least then i used .20s and it shot at least 400+fps, haha excellent, everypne thought it was just a normal AEG but it scared the heck out of them with the rate of fire, i use 9.6 battery. overall excellent (extra mags recommended)
by Perry I. on 05/18/2012
"This gun is the best quality gun so far that I had fun feels like a $500 gun. Shoots 23 bbs a second with a 11.1 lipo which i highly recomend and about 400fps. All around excellent gun!!!! Only thing is the bbs could get tighter groupings so I got a 6.01 tight bore madbull 509mm and a silencer this should be the best gun on the field;) another thing is the mag is to tight And hard to put in and out.

-realistic weight
-Chrisp shots
-lipo ready out of the box
-high rate of fire
-great field gun
-full metal except pistol grip,stock,and hand guards
-solid v2 gear box

-Non so far
-Hopefully the barrel goes in fine!!

"I received this aeg a while ago and have used it on mainly field events, no cqb. This aeg has better range than I thought, and can reach out farther than most people on my time. I run .25s and recently chrono'd at a steady 360+ fps. I run a 9.6v 1600mah nunchuck that is an extremely tight fit. The front doesn't quite close all the way. There is a tiny gap that is hardly noticeable and does not affect performance at all. THe ROF is great on this thing though. I highly recommend this aeg. I have had only one problem with this aeg feeding ever, and that was with the dboys mag, not KWA mag. After tinkering for a couple minutes it was feeding again.

Full Metal
Real weight

Upgrade-ability (As all KWA's are hard to upgrade)
Does not come with battery

All in all this is a great out of the box gun. You'll be better off than a lot of people from the start.

"This is a very nice gun, it feels great, looks great and performs amazingly. The accuracy is decent you can easily buy a inner barrel for like 30 bucks to fix that. It's full metal every where except the hand grip, hand gaurd and le stock. Shoots very very fast and has a good fps of 400fps. I have used it in a couple battles and worked just great. Right now I have the fast shooting gun compared to all of my friends. The hand gaurd wobbles a little bit and is a pain to battery's in. Only 8.4v brick battery's fit in it. A9.6v nun chuck won't fit. Mags is nice and ones you get from thee holy cow deal, which you should get, are nice as well. Mag wobble very very little. The hand gaurd btw doesn't seem to be very high quality plastic com pared to hand grip but it's still nice. It's a field gun for sure but it can used in cqb I only play in woodland battles so I would know for cqb.

Rate of fire
General feel
Looks cool
field striping is easy too
Amazing gear box best out there

Hand gaurd sucks for battery's, And isn't the nicest plastic
Accuracy kinda sucks but easily fix able

"I just got this gun today and it is amazing. it has great range and great rof(scary fast). if you have the money i would definately spend it on this.




internals are top notch


by tom g. on 03/11/2012
"This gun is awesome. It has great range and accuracy. I use a 9.6v and the trigger response and ROF is great but i would recommend a LIPO. KWA deffinatly is one of the best brands.

full metal body
sick accuracy and range
its a kwa

cant think of one con
by Payton H. on 03/09/2012
"This is the most amazing m4 I've ever used!

400 fps
long lasting
full metal
comes with 3 mags!!!

occasional hop up jam (but easy to fix by turning it upside down
by Michael S. on 02/21/2012
"This is an incredible product made by an incredible brand! Those who purchase will be satisfied and all those who encounter it will be converted! The KM4 is great out of the box and ready to dominate the field providing you with a high fps that is within legal limits of most fields (400 fps) mine specifically shoots 380-390, a stock tight bore which is accurate and precise, and the reliability and dependability KWA is known for. I've used the KM4A1 every Saturday for the past 2 months and I love it!

Using the Holy Cow deal and purchasing a 9.6 2000mah battery you are more prepared than 90% of starting players! I recommend this AEG to all of my friends getting into airsoft, because I want them to have a great time playing and keep playing and that's why I recommend it to you!
by jacqueline s. on 12/22/2011
"This gun is amazing.

Rate of fire 23 bbs with lipo a little hard fitting the brick type

gun is long lasting and kwa includes a 45 day warranty and will fix it even after the warranty with a price.
by chris w. on 12/06/2011
"there is only 1 word to bescride this gun AWESOME. i painted my foregrip, pistol grip, stock, and flash hider od green and its looks even cooler. i would recomend painting it a color you like (ONLY if you are a good spray painter; you dont want to screw your gun up).

-great price
-full metal
-awesome fps(even with a 8.4; even awesomer with a lipo)
-awesome rof
-the mag capability is not for all mags(that only means you dont use crappy mags which your not suppose to do anyways)
-the gun is very reliable
-on another review Tristin T. says the flash hider is hard to get off but there is a very small hole in the flash hider if you take the screw out with a allen wrench the flash hider comes right off

-absolutly none other than the battery compartment dosent fit a 9.6 so dont order a 9.6 with it like i did

overall this gun is a very well made gun by kwa probably the best m4 for the price not ony do you pay for the name but u also pay for the quality.
by Yang C. on 11/12/2011
"This gun is amazing. With a 9.6v or 10.8v battery, the ROF is insane. I can hear almost no gear whine when firing this gun.

Great ROF even with a 8.4 or 9.6
Nice FPS, consistent 400 fps
functional charging handle

My gun came with a scratch on the side but no big deal
no functional bolt catch
mag compatibility sucks

PS: take advantage of the 2 mags for $5 holy cow deal. I received 2 dboys full metal hi caps and they fit fine, they are tight at first but eventually wear in.
by Tristin T. on 08/27/2011
"This M4 is deifinately my favorite in both quality and performance! Its full metal besides the stock and handguard; and yes the flashhider is also metal. I recommend using .25's for the best accuracy. It still works fine with .20's but for the best accuracy I's still reccomend .25's. I currrently am using a 2300mah 9.6v nunchuck and its AWESOME. Now for some pros and cons...

Full metal
Accuracy w/ .25's
Realistic Wieght
Numbered positions on stock (0-5)
High quality trademarks
Battery easy to put in

Flashhider is impossible for me to get off
Wieght of gun can get tired after awhile if your not used to heavy guns or not strong

That's pretty much it guys!!! BE SURE TO DO YOUR HOLY COW DEAL AND GET 2 MAGS!

"Had this gun for six months now and it is the fifth gun I've owned. Have owned Tokyo marui, classic army, a&k, Cyma, Ics, and echo1(that's more than 5, I've owned 8 now) and I can confidently say my kwa is the most solid by far hands down! I put a full stock on it, a noveske 10" rail, a custom length outer barrel, and a 6.01 mad bull inner barrel. Kinda loud, but super reliable internals. Ripped my bucking (stock) so replaced it with a firefly I had from an old project.

Now the bad. I am no fan boy but still the best gun I've ever owned. Convertible outer barrel? Not really. True it is 2 piece, but mine sheared trying to separate the 2 sections. Luckily I have friends that can weld aluminum otherwise I would have been buying a new one. So slightly shortened for my 363 inner barrel.I use Lonex mags which are a ridiculous tight fit( look them up, best high cap ever!!) . only other gripe, optics/ carry handle rail on top of the receiver came loose. Can fix though, look on kwa USA forums, lots of diy info there. Overall super good gun, if I had the money I would buy another. Cons are minor, highly recommended

"I bought my KWA M4 at Christmas time and have used it ever since. It is a great gun!
Good ROF
Good Range (once you play with the hop up)
strong construction
When you tell a noob with a $140 Jing Gong M4 that you have a KWA they get a really funny look like "oh man he is going to kill me with his awesome gun." :)
really picky with mags
hop up takes lots of time to get the maximum range
Battery compartment is small so it is hard to fit batteries.

Basically this gun is perfect for the noob who wants to start with a gun that is amazing out of the box and the pro who wants a gun to build upon to outperform the competition.
by Ben J. on 02/27/2011
"This gun is hands down the best M4 AEG on the market in both performance and overall appearance. I would totally recommend this to both advanced and beginning airsofters. You absolutely cannot go wrong with KWA.

Amazing High Quality Externals
2Gx gearbox is the best on the market
Hop-up is exceptionally good stock
20+ rounds per second and amazing ROF with 9.6V battery
Very accurate with matrix .25 gram BB's
Very good 350 round Hi-Cap
Realistic buffer tube markings (numbers visible for every position 0-5)
Clean laser engraved trades
Crisp fire selector
Satisfying trigger pulls
High quality polymer pistol grips and front grip
Cool sounding functioning charging handle
Customer service for KWA is amazing like none other
45 day factory defect warranty
You really don't need to upgrade it internally ever and I recommend not doing it
Bright orange paint on the flash hider
You might not have one yet... but you should
Its accuracy isnt that great with .20 gram BB's but it is intended for use with .25 or heavier

Over the years I have owned and seen many airsoft guns but this gun is THE BEST par none
Thank god for KWA!
