KJW joined up with Tanio Koba to bring us their latest revision to their M4 Gas Blowback Rifle project. Running on its own proprietary gas system, the KJW GBB M4 RIS is remarkably efficient. The blowback system generates a healthy amount of recoil, giving it a very realistic feel. The rifle comes standard with a blank receiver which is perfect for custom engraving any logo or insignia you may want. Externally it's built solidly and when matched with the steel reinforced internals it provides a great out-of-the-box gun. The M4 RIS comes standard with front and rear flip-up sights, a RIS front end, and rail panel covers to match.

"The KJ Works M4 RIS is an extremely solid gun. The price that it commands justifies not only its cosmetic appearance but the astounding quality of its performance. KJ Works has built one of, if not the finest M4 GBBRs in the market. The "Training Gun" title is also deserved as all moving parts function in the same way as its real life counterpart, as well as the nice kick it provides. The look and feel of this gun is unprecedented. Out of the box, it practically requires no upgrades.
This is a gun that I have brought twice which is a testament to its performance and presentation.

"1 week i received my packaged, but the shipping cost in canada is expensive, the important thing is i got my packaged without worries. Thanks....

"I received mine about a week ago and have shot it every day since. It hasn't given me a bit of trouble Yet...

Then again, I'm a bit of a stickler when it comes to maintenance and preventive care. The very first thing I did, (and do after every shoot) is break it down and apply a very liberal coat of Teflon penetrating oil I got from my local hardware store. I ordered the metal flash suppressor, some Green Gas, and some of the .28gr. Match grade B.B.'s. My only regret here was not buying another magazine. Reloading DOES take a small bite out of playing time.

As a tactical MA instructor, I bought this as a low cost training aid for use in some of my weapons familiarity/weapons defense classes. The realistic weight, feel, look, and operation of the KJ Works Full Metal M4 RIS Airsoft GBB Rifle was the main set of selling points for me. And in this area it has met or exceeded all expectations.

Like I said, it hasn't given me any trouble "yet." Hence the very positive review. It's not that I "expect" there to be any, but the gun really demonstrates the forces applied to the various parts at any given time, this is evidenced by the decent level of recoil. But it highlights the need for these guns to be of very high quality, and a from a proven and reliable design. As close to the original as likely possible, I'd say the design seems pretty strong and not overly complex.

Accuracy. With the open sights supplied, It only took about 15 minutes to sight it in. And (I kid you not) I hit dead center of the Bulls-Eye at 25" on my very first shot. (I saved the target :)

All in all... These are expensive tools. And they are VERY expensive toys! But for what it's worth, I think mine was definitely worth it. I've gotten kind of a kick out of plinking with it when I'm not too busy answering questions about it after class. (And the "Full-Auto" is a gas!!) :)
