thank's

they came out right after i upgraded my gun it should be about inline with systema

I will update as soon as i get a chane to pass a chrono on it but it draw som many juce from the batterie that i 'm able to shoot 6 mdi cap and the batterie (8.4v 1400mah mini) is dead

Well it seems that i must have not charged my barrerie enough.

Any ways for those who will order a mad Bull spring you woud compre them to systema spring in terms of FPS.

My m100 did give me 360 FPS (m4 s with spring, bushing and a madBull tight bore of 363mm)

m110 shoud be around 380 fps
m120 shoud be around 390 fps
m130 shoud be around 400 plus fps

All this based on the result of a m100.

I have a Madbull 130 in a Systema mechbox. Last chrono'd around 460 fps.

I only have the poor man's chrono availible but,

with a m130 in a ca249, it will puncture the top of the can.
with the m120, it will just do the bottom edges, only dents the top/

shit, i want one in my gun
