"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.

Pros
-All Metal Construction
-Rails included
-Crane Stock is sturdy
-no rail wobble
-accurate
-can draw blood...lol

Cons
-None

"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.

Pros:
-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)


Cons:
-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.

PROS:
amazing accuracy

22 rounds per second
all metal
really solid feel battery lasts all day

CONS:
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.


Pros:
built very well/solid
great performance
high rof
perfect fps

Cons:
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.

"Awesome gun!!! I've had it for about a year now and run it dmr style but it's very versatile so you can run it basically how you want.

I have mine upgraded internally pretty heavily and it's shoots 225-250ft (keep in mind that mine is upgraded so it doesn't shoot that far stock)

Pros
Full metal
High quality internals
Hi rof
Versatile
Feels good in your hands

Cons
Only shoots a little over 150 feet stock(which is fine for some people not for me)
Scratches easily
U don't have it

Overall I think it's a good gun and it has served me well
by Justin N. on 09/14/2014
"I have both the KWA SR12 and the KWA SR10, I like the performance of the SR12, but the SR10 has some down falls on it. I noticed that when shot the pellets drop fast, maybe around 100-150 Feet. I noticed that many people have this problem, so it's not just a bad Egg.

Pros:
Sturdy feeling
Very realistic
Removable orange tip

Cons:
Heavy!
Not for young!
Does not come with a battery or charger
Early pellet drop.
by Jayben S. on 08/25/2014
"Great gun! Took out of the box went outside and shot it. My friend and I were a little disappointed with the range right out of the box. I think the internals are amazing. It shoots amazingly fast. The externals are a really solid. I'm pleased over all. It is a heavy so if you like fast run and gun play this isn't the gun for you.
by logan w. on 02/20/2012

by Owen R. on 11/28/2011
"I must say that this gun is extremely high quality like most KWA products. However it pains me to say it the only thing that makes this gun worth the nearly 400$ price is the 2GX gearbox, most of the things that makes this gun different from the SR7 and SR5 series is the length of the barrel and rails which doesn't seem to be worth the extra price. However with the high-torque gears and motor this guns ability to perform extremely well for a good duration of time does make it worth the price.

I recommend if you are interested in this gun to definitely get it at evike.com due to the price margin. I bought mine from a different website and i regret this. Its about 10$ cheaper on evike and the extra mag deal is amazing.

P.S. I recommend against this gun if you are afraid of working on your own gun. Although KWA products do last, it will eventually break and this gun is by far one of the more frustrating AEGs to work on that i have ever experienced. (even if you dont like working on your own guns many people you can pay to fix your gun will groan at the thought of fixing a KWA)
by Petr B. on 02/06/2012
"Pros:
Build quality
Quick detach sights
Good performance out of the box
Unique weapon design
Smart made crane stock
Reinforced gearbox
Some gearbox internals (not all)

Cons:
9mm bearings they literally blow up and destroy your gears
Strange barrel lenght
Price/performance is low
NOT Li-Po ready unless you change tamiya connector and wiring+mosfet

So, to sum it up if you are not scared of working on your gun if it would broke and believe me it will eventually, get this gun its unique designed good quality except for 9mm bearings (oh and my friend have SR12 and same thing happened to him), but honestly for the price 385$ I would expect a little bit better stuff.

"Bought this airsoft gun back in 2012, and unfortunately i was generally disappointed in the performance of this weapon.
It worked for 1 week, then started jamming every single round, found out the rubber was already worn out, so i changed it, here i noticed KWA's 2 part hopup chamber, and this is where the bad things start happening.
I changed most internals of my weapon, as i do in all my weapons, and the gearbox did a steady 420 fps after my modificatins, this is in another gun, reinstalling it in the KWA, it dropped to an astounding 150 fps, suprised i was, and fixed every single leak i could find, but with no results. Turns out the two part hopup CANNOT hold its seal, i bought another from the KWA store, and no change, the hopup simply does not keep the air in, as it can easily escape between the two pieces of plastic.
Therefore i must give this a bad review, as you are not able to ever use a 1 piece hopup, don't buy this gun, in the long run it will loose it's seal.
