...Thought it might be better to change to silicone. HPA can diesel right?

...associated with a bit of oil and/or grease in the reservoir.

i think it would be impossible to ignite , except maybe in the barrel where air is mixed , but nothing fatal there. ill get body armor and test it lol

...which can damage a gun, just wondered if PCP is the same. Not that daft a question surely?

was well answered by steve, its no issue whatsoever.. adiabatic heating and/or dielseling takes place in springers, no such effect in pcp/

But they do it - not because the air in a springer's compression chamber is compressed to high density (actually the compression ratio of a typical springer is only about 40:1 - much less than a PCP charge at about 200:1) - but because it's hot - about 2000oF.
