*** All the new APM50 have the hopup disabled and the users should ignore page 13 on the older version of the instruction manual ***

Important Notice

APM50 Hop Up was removed since 2014. We found that Hop Up do not work well on our high power APM50 using Co2. Because APM50 is powered by Co2, the velocity is too high (Usually over 600 FPS) and No Hop Up Bucking can take it. We will not answer any enquiries regaring to add Hop Up or buy Hop Up parts for this gun model


Base on the idea of APM40A3 Spring Action Airsoft Sniper Rifle, Hakkotsu now develop another new series  APM50 a Cartridge Ejection Airsoft Rifle which is powered by Co2. This gun will be available for sell in early 2013.

Airsoft Guns powered by Co2

Similar to its brother APM40A3, APM50 is also a bolt-action gun but power source is coming from Co2 stored in the cartridge. With the worldwide-patented cartridge design, User can simply charge the Co2 from an adapter to the cartridge. Standard Guns comes with six Co2 cartridge, one magazine and one refill adapter. The most important thing is, the cartridge is refillable and available in 6mm caliber, which is common used and found in Airsoft market.

High Power and Multi Purpose of Using

Since APM50 is powered by Co2. The Power and Velocity is higher than usual. According to our measurement, the velocity can each 450 FPS in 0.2g BB.


As APM50 provide you a real feel of recoil and handling. The cartridge case will eject every time you shoot and cock. The ejected cartridge case of course can be re-usable and refillable for your next use. The bolt can be completely removed by pressing one button just like the real gun. APM50 has been built heavier and added texture, which make it looks fantastic and real when compare to others Airsoft Rifle


In APM50, the Co2 gas is jetting out from the cartridge directly. There is no spring-piston action involved, so the vibration of the gun is minimized and the operation noise is 50% lower than other Airsoft Gun. Meanwhile, the Co2 is coming from the small cartridge case and fully used per shot, so it gives excellent shot to shot consistency over a range of pressure as the air reservoir is diminished. Low Vibration and consistent velocity shot to shot makes our APM50 superb in Accuracy.

Inherit the advance features of APM40A3 Spring Action Sniper Rifle

Since APM50 is developed from its brother APM40A3, our APM50 inherits the advance features coming from its ancestor. For example, Removable Butt Stock for easy transportation, Adjustable Creek Pad to best fit the user,  Precision Inner Barrel (Perfect straightness) to increase accuracy.

Lower malfunction rate

Since the power source and main mechanism are now coming from the cartridge case instead of the gun. So user can simply repair the cartridge or use a new cartridge in case of malfunction happened. Users will not feel despair when malfunction happen while battling. Extra Co2 cartridge case is just cost USD$5 which is affordable by public.

To conclude, APM50 is a brand new gun that never exists in the market before. It is a unique, accurate and realistic rifle.
