Airsoft Canada - View Single Post - CA-25 munching pistons

A friend of mine brought me a CA-25 that was only shooting about 270fps. Upon closer examination it had the usual poor air seals associated with the CA-25 and a damaged piston (2 damaged teeth behind the metal ones). So I dropped in a CA bore up kit to improve the air seals, replaced the gears with modify torque up gears, replaced a damaged piston and put in a stiffer spring (to get it back up around 400fps). Things seemed fine for a few games but then the gun completely stripped all the teeth off the piston. I went back into it, replaced the modify gears with CA gears and dropped in another piston. Once again the piston was stripped clean. If anyone could suggest what might be the issue here I would greatly appreciate it.
