The SR7 is the ideal close quarters weapon. Tuned for high speed, the SR7 fires at over 20 rounds per second yet maintains a velocity of approximately 350 feet per second within the limits of most indoor arenas. The SR7 features full alloy construction, MIL-SPEC-1913 picatinny free floating rail adapter system, 2GX Gearbox, 2G High Performance Bucking, adjustable flip up front and rear sights, flat top receiver, matte finish with individualized serial numbers, 6 position collapsible crane stock with two integrated battery compartments for nun-chuck style 11.1v Li-Mn batteries or 11.1v Li-Poly cell packs.

At the heart of every KM4/16 series rifle is KWA's Second Generation Extreme (2GX) gearbox, designed to resist cold temperature failures. Structural reinforcement has been engineered into the shell strengthening the overall integrity of the gearbox especially in areas prone to failure. The 2GX comes standard with six 9mm Spherical Bearings and Heat-Treated Precision Gear Sets offering flawless performance in all conditions.

Accuracy of the rifles has been greatly enhanced with the introduction of the 2G High Performance Bucking.

"The KWA SR7 is the best AEG out of the box you can buy, period.

In June of 2011, I bought my first SR7. Over 7 years and thousands upon thousands upon thousands of BBs later, it still runs flawlessly on an 11.1v LiPo.

The gun has hit the ground hard many times - I even fell on it once - and it still is extremely accurate and the parts are almost all in perfect working order.

Devastating accuracy high fire rate (especially on an 11.1, about 25 BBs/second) insanely solid construction short but customizable 7 in rails = best gun for anyone (newbie or experienced player). I would recommend the SR7 to anyone!

"Hands down, probably the best gun starter gun. This was my first airsoft gun over a year ago, and still always reliable. Love this game.

"PLEASE READ - This may be the best M4/MK18 for the money.

I've had this gun for a little less than a year, but I've taken this to the field many, many times. Since there's multiple things I REALLY enjoy about this gun, I'm going to segment this review into three parts.

1. Build quality:
KWA has made the sturdiest MK18/AR15 style AEG I've ever used. The metal is extremely resilient and you can buff out most scratches. The parts are incredibly durable and it comes out of the box with no wobble from the rail. Something extremely important to note! The stock DOES wobble a little out of the box, but this is 100% fixable. If you're buying this gun I suggest you get a really long phillips screwdriver, push the stock down to its lowest notch and screw that sucker up nice and tight. Eliminates the wobble ENTIRELY. Please don't let the "stock wobble" from other reviews deter you. It's incredibly flexible. If the rail, god forbid, does ever wobble you can tighten the 8 little screws just after the delta ring just under each rail toward the base and its solid again. Now if you happen to LOOSE the screws, I have great news for you.

2. Performance:
Shoots HARD and fast. Very accurate with minimal spread over a good distance. This gun already comes pre-upgraded and honestly you won't even need to upgrade it any further. This is honestly the best AEG I've used for CQB and even thought its rated for 360 FPS it hurts quite a lot.

2. Part availability:
Now with KWA I see a lot of reviews from even Evike staff saying KWA guns have proprietary parts and of course it does to some degree with it's system, but the main reason besides the two reasons stated above that I prefer KWA above anything else is the part catalog listed on their site if you lose or break anything. I actually lost a couple of screws that came loose from the rail system (the bottom most ones out of eight) and the rail became wobbly. After I discovered the issue, I looked on their site after consulting the gun manual for the part list that the gun came with (DO NOT THROW THIS AWAY). I actually noticed they sold a variety of barrel lengths and I wanted to get a suppressor, so I measured up the right size and it fit just like a glove. This is one of the biggest reasons I love KWA and I know that if anything ever goes wrong with my gun, I can order parts from the site. I haven't seen any other retailer do this and I recommend shopping on KWA's website.

Honestly I think I'll be shopping KWA for all of my future airsoft guns. Their prices are hard to beat and they build quality guns with good performance out of the box. I just LOVE that I can easily buy new parts and it's a god-send.
