The ACP603 is powered by a .12g Co2 canister, a very common and readily available power sourse. Simply inserting one Co2 canister allows you to fire up to 70 rounds. There is no denying that Co2 works better than Top Gas (Green Gas) in cold weather. APS charged and operated their ACP601 in 5°C / 41°F and the test results were positive. The Action Combat 603 works better than any other Top Gas guns in extreme weather. With the Conversion Kit use, the barrel is now extended and meets Canadian legal import velocities. The velocity of the SMG goes up to 430 FPS with 0.20g BBs, which is beyond comparison than any other SMG.
Aftermarket parts compatibility
ACP603 use's common parts which are compatible with the major leading brands in the market. For Instance, the Co2 magazine can be used with TM and WE pistols. Future upgrades and modifications are possible. Performance parts can be used and external accessories can be mounted. The ACP603 is designed for Airsoft War Games or upgradable to professional IPSC gun use.
Unlike other Co2 Pistols in the market, the ACP Pistol has a unique upside down cartridge insertion design in the magazine. With this design, the magazine will act as a regulator, allowing Co2 flow within the magazine first before going to the chamber. This technology stabilizes the Co2 pressure inside the mags, thus giving you a more stable shooting velocity for each shot.
