I havent gotten close to the magic 740. Best I've been able to come up with is a ~410 FPS gun shooting .43 BB. or about ~650FPS w 0.20. Those things are impossible to close the shell on. I had to get another guy to hold the cylinder down and table vice the gearbox in place. I used a long screw driver and had to push with basically my entire body weight to get the spring into the box. Without a second person I wouldn't be able to close the box. Parts list:
Prometheus Cylinder,
Prometheus Cylinder Head
Prometheus Nozzle
Prometheus Tappet Plate
Prometheus Triple torque gears
Prometheus Aluminum piston head
System supercore piston
Airsoft Surgeon stage 6 spring
G&P Gearbox shell 8mm
Kanzen 8mm ceramic bearings
G&P hopup unit
TM barrel
Systema spring guide
Prometheus Cut off lever
G&P Switch
AJAX STS
Systema Magnum motor
11.1 Flightpower pack 4200 mah 40c continuous.
Hopup teflon mod
Cylinder head mod.
In the future i might try this again but with a stock TM gearbox shell and a bore up kit. Still looking for a not damaged TM gearbox shell to use.
