The concern I have is the nozzle o-ring. In current PTWs using Viton o-rings, they need to be replaced about every 10,000 rounds. The newer cylinders are using polyurethane, and so is the Revolution mechbox. There is no word on lifespan for those yet, but it will exceed 10,000 rounds for sure. But, to replace it, you need to tear the mechbox down.

According to Blackwolf from airsoftmechanix, the MP5 PTW cylinder is smaller in diameter than the M4 cylinder, and this is a real problem for cross-compatibility. Both he and Zilch from Systema Europe are sworn to secrecy (as it were), so no further info is available from them to be 100%.
