well
i have a CA M15 with at fixed stock and a silencer on so i can have a bit longer barrel 470 mm.
the setup is as follows
G&P 7mm bearing Gearbox
systema infinite torque gears
systema new bore up set for M16
systema hop up unit with black guarder bucking
Guarder blue half teeth piston
systema bearing spring guide.
guarder SP170 spring.
Eagle force hummer 1300 motor
1,5 mm^2 wiring
12v GP 3700 mah battery
Fixed stock for M16
Guarder mildot 32x4
currently it shoots an 0,2 ICS bb out with 185 m/s or 610 fps
which gives me an engagement distance of around 80-90 meters with straight 0,36 bb which it fires with 125 m/s or 412 fps
it works really nice and at 50-60 meters it is dead accurate. i can easily hit a torso with 1-2 shots no problem and at 40-50 meters it is possible to head shot some one consistently, and i still dont have a prometheus tight bore in it.
