ics m4 sportline piston assembly

[ikarma70]

Hi all, got my m90 spring today and started to strip the piston assembly and some parts went flying.

the parts i have on the bench after some searching are: 2 split halves, 1 black plastic nozzle, spring guide and nut, 1 piston sleeve and piston, 1 small looped ended spring.

what does the small looped end spring connect to?

hope someone can help!

It connects the tappet plate to the gearbox.

Thanks bud, all sorted out and the gun shoots much much smoother, less aggressive and feels like it has a higher rate of fire with the M90 spring in.

Not chrono'd it yet but it is a vast improvement.
