  • Product Description

    KJW joined up with Tanio Koba to bring this M4 Gas Blowback project to life. Running on its own proprietary gas system, the KJW Gas Blowback M4 is remarkably efficient while still generating a healthy amount of recoil giving this rifle a very realistic feel. The rifle comes standard with  blank receiver to allow the player to customize any logo or insignia you may want. Externally this rifle is built with a solid heavyweight metal alloy construction and when matched with the steel reinforced internals, it provides a great out-of-the-box gun that is extremely reliable. The KJW M4 RIS comes standard with front and rear flip up sights, a RIS front rail, and rail panel covers to match. The Rear Sight is detachable, revealing a 20mm weaver rail perfect for any scope or red dot sight. This rifle also features adjustable hop-up located on the ejection cover, giving you the ability to adjust your shot for range and improved accuracy. Take some of the weight off this heavyweight gun (11 lbs.) by adding any single, double, or triple point tactical sling. The 30rds magazine is constructed of a body made of aluminum alloy and is based off the Canadian design and is unique among the GBB Carbine collection. These magazines offer a larger gas and are more efficient for better performance. The KJW Gas Blowback M4 offers a realistic buck into your shoulder with every trigger pull and offers up to 450 fps (Top/Green Gas) for outdoor games or low 300 FPS(HFC134a Gas)  for close quarter battles
