For an Osprey suppressor (or any suppressor, for that matter), what's an effective method of cleaning carbon buildup out of the hole into which the piston goes? Pistons are getting more and more difficult to remove without using a hook of some sort, and they meet some resistance about halfway down when inserting them. I've confirmed visually that it's caused by carbon buildup. Scraping it out is one way, but that can damage the walls of the hole if one's careless.
FWIW, I need to switch pistons occasionally because Glocks and H&Ks, for example, need differently-threaded pistons.
