PLEASE NOTE ALL POLARSTAR ENGINES NO LONGER COME WITH A QD FITTING
The Jack allows for easy velocity adjustment. Using a standard M4 as an example, velocity can be adjusted from below 100fps and up to approximately 500fps with a .20g BB. Longer barrels will increase the maximum FPS while shorter barrels will decrease it.
ROF: 30RPS+
The maximum cyclic rate of the Jack is affected by several factors, however, 30 rounds per second is a conservative number. Most configurations will exceed this easily.
Comes with FCU (fire control unit), wire harness and trigger board
