Please bear in mind the barrel should be cleaned from breach to muzzle end and allow the cleaner to rotate freely along the rifling. This is why I use a bit of string and cleaning cloth as it allows the cloth to follow the rifling down the barrel. Also by not pushing from the muzzle end you wont push any crap into the port where the air comes from thus putting unwanted crap anywhere near the internals. I adopt this procedure even when I do occasionally clean my rimfires and they are a lot more dirty and have lesser tolerances than any of my pcp's/springers. Just another question when you bought second hand did the previous user use it on a regular basis. Also was it clean and tidy, ie no rust visible anywhere.
