The KWA KM4 SR7 was specifically designed for high level CQB players and offers a huge number of factory upgrades and improvements over the standard metal gearbox M4's. The SR7 DEVGRU was based on an M4 variant developed for the US Naval Special Warfare Development Group. This KWA M4 offers a full metal alloy body making it durable and giving it an extremely realistic look and feel. In addition to the metal body the gun has a 7 inch metal free float quad rail system that allows a large number for different accessories to be easily mounted. The KM4 SR7 DEVGRU was designed for CQB specifically and offers a CQB legal FPS without the need to change the spring. The shortened barrel and adjustable stock make it easy to maneuver around in those tight spaces and urban style environments. The gearbox in this gun is the redesigned 2GX version 2 gearbox which makes it amazingly durable compared to the standard gearbox and nearly all aspects of the design have been improved. The crane style stock allows up to a 9.6 small type nunchuck or small LiPo battery to easily be fitted into the stock giving it an amazing rate of fire. This extra durable gearbox makes this gun LiPo ready out of the box. KWA makes some of the finest guns available for high end competition play. If you're looking for an amazing CQB M4 RIS with high performance and durability without having to do a bunch of upgrading and work on it then this is a perfect choice and will not disappoint.

**This airsoft gun comes with a permanently affixed blazing orange tip as federally required, not show in stock factory images above.

    First order

    This was my first order from I just happened to find a video on Youtube which spoke of so I figured I would check the site. I was in the market for a SR7 or similar AEG, and couldn't believe the price they had it at, far less than other sites I had seen. So I took a chance and it was worth it. The gun got here in good time, shipping was free, and it came with a free shirt. Everything was as advertised and I can't complain about a thing. Will order from here again!

    You pay a lot, but you get a lot.

    Honestly, this awesome AEG is made better than quite a few real firearms that I've handled. I know the pictures don;t tell the full story and photoshopped $100 gun could look just as good as a $300 gun. But once you get one in your hands, you'll feel the difference. This KWA product is a bargain, but because it offers a great value. From the usage standpoint, it's heavy (all metal after all),so I definitely recommend a sling. The grouping of shots is excellent and so is the accuracy. Perfect all around gun and not just for CQB.

    Quality Product

    Out of the box, the KM4 SR7 delivers. Pros: Accurate, easy to install and remove batteries, shoots with authority, easy to stay on target. No need to adjust the hop-up out of the box. I left as is, and it shoots fine. I've only had for a week, and have used it once so far. It hits the target hard and accurate. Cons: Battery cover feels a little loose, but so far it is not a problem.

    Expensive but really reliable

    If you want the best all steal construction CQR look no further it is build really well and I love all the details on the gun. It shoots low enough that you can take it to any CQB field and play with no issues. I would use .23 and higher to get the best distance and accuracy out of it but asides from that pop a fresh battery and have fun.
