Guarder Half Teeth Reinforced Piston for Airsoft AEG

"So far so good! I'm pushing a SP160 spring which is equal to a M170 spring through 5k rounds. I'm not sure why others are stripping this piston when mine still looks and function flawlessly. Hopefully everyone isn't going crazy all out full automatic on this thing and that can strip any piston out.

"Designed to fail! This piston came with my Guarder bore up kit that included an m150 spring, it failed just after using have of my clip, the first tooth completely broke off. It says it will hold up to an m160 spring. There is no way. Now I have to spend another $20-$30 for a new piston.
