"This piston is quite weak. In every gun that I have had this piston in, the rack gets ripped out the back even after using epoxy and superglue on the piston rack. Granted my builds are around 400 or so FPS with .25 at around 29-35 ROF depending on the build, these pistons are not as strong as they make it seem. Save your self the time and get an SHS piston. Much stronger and will last much longer. If you want a piston for a stock gun just to increase reliability, this will do the trick. But take a gun techs word and get the SHS piston.

"This piston cracked after 7 hours of play. My setup throws .28s at 400 Fps at 35 Rps. Very Disappointed. I should have just bought an SHS from the beginning.

"I just got this piston and stuck it in my Matrix PDW and fired maybe less than 100 rounds before the first tooth on the strip broke. Granted I do have a high speed motor, LiPo battery and an m120 spring so it is putting a lot of stress on the teeth. I may have just received a lemon or maybe this piston should only be used for lower powered guns. Either way I am going to try to find a much more durable piston this time around.
