"I just bought this gun a little over a month ago and i just took it to my first airsoft war yesterday and let me tell you it was one of the best guns out there.
the range and the rate of fire was one of the best in the field
the range was even beating most of the sniper rifles
the rate of fire was better than most guns out off 200 ppl other than about 3
it comes out of the box shooting 380+ with .20s
if you have the money for this its well worth it

"I am getting this gun in about a week and i am very excited! I have heard great things about this gun and i am debating on whether to get rail covers and a holo sight or a lipo battery and charger. Can't wait to buy this gun! I would recommend it to anyone.... It's KWA!

great gun, best value for the money.

"I've had this gun for about 8 months and it is a beast. I have the most range on the field. I have attached a red dot acog, silencer, and grip. The only bad part is that with everything on it, its as big as the SR12 and weighs twelve pounds. I'm only 13, but its well worth it. Buy this gun. You wont regret it!

"This Gun is AWESOME! It shoots fast, accurate and doesn't have that tingy sound a cheaper AEG Has. It also has a little bit of kick with full charged Battery. For a starter who has the money or wanting an M4 Upgrade, you have seen the right gun. Make sure you use .25s, right on the box it says that, and you would get better performance if used .25s or .23s.

"This gun is amazing. It shoots fast, hard and accurate.

Just FYI the front sight in the pictures is backwards.

"I got this gun and it is by far the most amazing gun I have ever had. Out of the box it is shooting about 385 with .23 bbs and about 20 rps! I am currently using a 11.1 lipo battery because in stock form the SR10 is lipo ready! I would highly recommend this gun to anyone who is serious about airsofting.

Gun is solid with absolutely no wobble.
Shoots extremely fast and accurate.
Has reinforced internals for a lipo battery.
Extremely clean with amazing attention to detail.

I honestly cant think of any...

"This gun is amazing, I would highly recommend purchasing this rifle. Out of the box mine shot around 390 with .25 gram bb's. It had a consistent fps and I was easily able to tear through a left over gingerbread house from Christmas. Don't let the price dissuade you it IS worth it.

-All Metal Construction
-Rails included
-Crane Stock is sturdy
-no rail wobble
-can draw

"This is a great gun for outdoor play, probley not to hot indoors because of its long lenth.


full metal
high rpm (11.1 lipo= around 2250 rmp)
good accuracy
great range
looks really nice

little bit heavy (im only 13 so mabay just for me)
picky about its mags (MAG's mags work well)

other then that this gun is great ive had the jg m4 and stag 15 and they dont compare one bit.

"Overall the SR-10 is a great gun, KWA guns truly are "Engineered to Outperform." I don't see how anyone could ask for more out of a gun for $385, it's that good. Certainly well worth the money.

-Very sturdy.
-Excellent finish.
-High quality materials.
-Amazing gearbox.
-ABSOLUTELY RIDICULOUS RATE OF FIRE, even with only a 9.6v battery.
-The 6.05 stock barrel is great out of the box accuracy.
-Right at 400fps.
-Very crisp trigger pull(very responsive), feels like it has a mosfet.
-Comes stock with a CQB-R sling adapter.
-Crane stock tells you which position it is in. (labeled 0 to 5)

-No real steel trademarks.
-battery wires are a little large but not bad. (most small type 9.6v nunchuck/butterfly type batteries will fit no problem)

Overall, I give this gun 5 out of 5 stars and would recommend the KWA SR-10 to anyone looking to buy a high-end AEG.

"This is an excellent gun. I've yet to have any problems with it. The rate of fire and FPS are great. Has a realistic feeling and weight to it. Has been a really reliable gun in airsoft wars. I would recommend this gun considering it's good for long distance and close quarters. I've had this gun for about 8 months and has been my primary choice in airsoft wars.

"i just got this gun and its a pretty good gun but it could have better range.

amazing accuracy
great fps
22 rounds per second
all metal
really solid feel battery lasts all day

great range but not good enough for my long range battles

overall this is probably the best gun i own and i highly reccomend it.
by Kathy H. on 09/01/2010
"Great gun, but of course it will be its a kwa !!
rof is amazing with a lipo. out of the box it was shooting 27rps and about 380.
money well spent :)

"This gun is awesome. Got it a while ago but only used it for the first time in battle a few weeks ago. Shoots 400fps out of the box and 16+ rps with a 9.6 battery. Seems to be a good hop up as the bbs keep a good group but a better hop up and a tight bore barrel would probly improve the performance even more. It is solid with no barrel wobble at all. This the first AEG I have bought and i wanted to best gun and I got it. This gun rocks in both CQB and outside fields. I would highly recomend this gun to anyone or any of the KWA guns. Just remember to use high quality bbs and the right clips for flawless operation.

built very well/solid
great performance
high rof
perfect fps

No real flaws but the longer then normal M4 barrel of 393mm will make it hard to find a tight bore unless to get a mock silencer so you can add a bit longer of a barrel.

"So i am now going onto my 3rd year using this same exact rifle weekly. I run a 11.1 on her and still shoots like an angel. I switched the barrel for a 14.5 inch, and still has the range that no one else has. With .25 and a 11.1 im still getting 340 fps. Theres many pros and plenty of cons but cons you wont notice unless working on externals of the rilfe. Pros are, she still shoots amazingly 3 years later. You could throw a 10x's zoom scope and a bipod on it as a dmr and still out range 90% of the snipers out there. Very hard punch behind it too. Very nice receivers. It does have your average plastic pistol grip and crane stock but trust me on this. This is the best crane stock you will own, i got rid of mine for a krytac and i regret it so luckily i found a friend with one and im trading for it. The stock did have a little wobble but just take it off and throw velcro under it on the buffer tube. No barrel wobble or anything. The 2 piece barrel is also a wonderful thing to have,rails are beautiful but that it where the cons come into play. This gun is near impossible to replace external. The rails have one of those delta rings that spin not the spring ones. I ended up having to saw it off to get the delta ring off to put a 12 inch daniel defense rail on. It will fit your gun. You have to hammer it on tho. You have to get the delta ring off in order to get to the barrel also i do believe i dont exactly remember. The stock is also a big pain to get off because the fuse is in the stock but is screwed down. So you have to unscrew it and throw electrical tape around it and throw it in you stock. The gun over all is the best gun i have used you cant go wrong with kwa, but when it comes to easy customization it gets a 1 star the gun id give 100 stars if i could.
