"I put this in my stock, Echo-1 G36c because the teeth on my polycarb started to wear down and eventually shattered into 3 pieces. This JBU piston is amazing. Looks nice, great construction. The only reason I give it 4/5 is because I recently installed a PDI 190% spring (Note:I looked at the piston when installing the spring and the piston showed no signs of wear from about 3 months of continuous use) and the first tooth on this piston broke off within a few shots. I'm sure that it's because I wasn't using a high torque motor though. Now I've got to buy a new piston and a high torque motor. I just Knocked off a star for its strength. I would have thought my motor would have quit before the piston.
Overall, Good buy. Would still recommend.
