I am upgrading my spring and putting in metal bushings. The bushing are in and the gears reassembled. I have been following guides on the internet, mainly the one at
http://www.airsoftplayers.com/mechbox/tutorial.asp. However, I don't know how to get the spring out of the piston/piston head on the ICS version. The piston head is very hard so I don't think i can cut it, and i don't want to try to twist it off because it looks like one piece with the piston and I would just deform the piston head. So in short, how do I get the spring out.
Thanks.
