The KJ Works Tanio Koba Gas Blowback M4 CQB is a highly refined M4 with a gas blowback system designed by the legendary Mr. Koba from Japan. With each pull of the trigger causing the M4 to buck into your shoulder, and offering up to 450fps on Top/Green Gas for outdoor games or as low as 300fps when using HFC134a gas, perfect for Close Quarter Battles! With minor modifications (if legal in your country), the KJ M4 can be upgraded to shoot in the 600fps range.
Save for the usual fire selector indicators, the body of the KJ Tanio Koba M4A1 is a featureless manse ideal for custom engravings or paintjobs. The combination of a body made of aluminum alloy with FRP furniture, makes this Gas Blowback (GBB) Carbine extremely robust, and feeling very realistic. The 30rds magazine is constructed from aluminum alloy as well and is based off the Canadian design and is unique amongst the GBB Carbine collection. The larger Canadian magazine design allows for a larger gas tank and more efficient gas management for better performance.
The KJ Works Tanio Koba Gas Blowback M4 CQB offers a great big BANG for your buck - and we mean BANG.
Although not officially sanctioned by KJ, some enthusiasts have found that the magazine can in fact take CO2 (charged using a Madbull CO2 adapter) to achieve even eye-popping velocities. Please check local laws before you upgrade this gun.
