I currently have a jg m4 with a MOSFET and low resistance wiring installed. And I was thinking that I would like to try a li-po battery for more rof. Well I tried it and it was somewhere between 35-40 rps. I have a stock piston so it is plastic, and I was wondering if the rate of fire would strip the piston. I had a friend who tried it in a ARES g36k and it striped the piston, but he held the trigger for quite a while. So my question is this, Would a plastic piston be ok with this rps if I just shot a few rounds at a time? Or would I need to replace the piston with a metal toothed one?
