In the case of the piston kit on an AR there is the addition of parts. The piston and shaft are moving. The bushings of the Adams Arms kit for example has to be pressed into the upper receiver. I suspect it will wear over time. With all the kits you have springs that will also need replacing. The piston and cylinder will also wear. It would probably a long time to the point where gas leakage prevents proper cycling.
