    I don't own a piston gun,but I would assume everytime you clean the gun,I'm going to assume that carbon is going to build up on the front of the piston and needs to be scrubbed off

    On a atandard AR15 gas system you need to clean the gun and bolt after every range session,Bolt Carrier Group needs to be broken down and the bolt back where the gas seal rings are needs to be scrubbed to remove any carbon buildup,also gas rings need to be turned so the splits aren't lined up allowing gas to escape,I use an AR15 chamber brush to scrub the inside of the BCG where the bolt slides in,also on the extractor push out the roll pin to allow cleaning behind it,then reassemble,I lightly libe the bolt surface prior to reassembly.

    If you are talking about cleaning the gas tube itself they make pipe cleaners that are long enough to fit inside the tube,I rarely ever clean the gas tube,the gas key on the Bolt Carrier group can be sprayed and scrubbed with a 22 cleaning brush

    So the only place that the carbon should build up Should be the gas key on the top of the bolt?

    You probably mean gas tube. It doesn't really need serviced too often. I've never cleaned mine, ever.

    It certainly won't hurt if you want to clean it, and may eventually need cleaned.
