Reply To: Dry firing….is it bad for a PCP?
I cant comment on Korean air guns as I dont have one.
The principle applies across the boards (makes) – dry fire down to @ 60 Bar then release the remaining pressure by hand – tricky if your cylinder doesn’t unscrew. On those that do unscrew a length of dowelling is usually used to knock open the valve (valve in the cylinder) even so you have to be very careful.
Damage to firing pin and main valves can be expensive & it usually requires replacement parts (ie. not a Home Fix job), I dont risk it.
