KJ Works Full Metal M4 RIS Airsoft GBB Gas Blowback Rifle
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.
