The JACK allows for easy velocity adjustment by changing input pressure and does not require different nozzles to reach its full velocity range. Using a standard M4 as an example, velocity can be adjusted from below 280fps and up to approximately 500fps with a .20g BB. Velocity can vary per model as longer barrels will increase the maximum velocity while shorter barrels will decrease it. The maximum cyclic rate of the JACK is affected by several factors such as the operating pressure as well as quality of the magazine and BB's used. However, 30 rounds per second is achievable in most standard configurations. Great Air efficiency, velocity range, and rate of fire!
- Easily adjustable FPS can be used for both CQB and field use without having to change nozzles
- FCU uncluded for easy programming of rate of fire and other parameters!
