Is it okay to dryfire an air rifle?

Answer 1

If you are asking about a "springer firing system" The answer is NO do not dryfire it.

When you shoot a single cock springer rifle or gun with a pellet in the chamber, there is a moment where the piston actually slows down just before the pellet is fired down the barrel. If you have no pellet in the chamber the piston slams against the end of the chamber and this will eventually ruin the chamber. Dry firing a Co2 gun will not hurt it. You will just waist Co2.
