KJ works M4A1 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 is remarkably efficient. The blowback system generates a healthy amount of recoil, giving it a 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.
