Hop up is a tough one to call. Silicone rubbers are pretty good at handling high temperature. In industry, silicone is often used for high temp applications. Unfortunately the flame front can get pretty damn hot. Well beyond what silicone rubber can handle. I thought about a way to spoot in a drop or two of oil into the sealing area with every shot to provide a film barrier which was sacrificial to protect elastomer parts. The idea was to keep them wetted so the liquid would absorb heat with firing cycles and keep the rubber part temps down. But then you get into barrel fouling not to mention the potential generation of carcinogenic/stinky crap with each shot.
I think we kind of suffer from being potentially described in an AOW kind of category as it is already, but I can see how burning stuff doesn't help assuage soccermom fears.
