It seems to me that make and model solely determine price of used guns. A few big named tuners can bring in some extra dollars, we know that. However, it’s always puzzled me that if we know that a specific airgun has variation and some are highly accurate and some simply wont shoot like the good ones, why are they resold at the same cost. I’ve always kept the majority of my targets, tuning notes and ammo testing documentation for every gun I’ve had. Every time I have sold a firearm or airgun the new owner gets all that information. I don’t understand why stuff like that doesn’t factor in within the airgun community. Maybe it does I don’t know, I haven’t bought nearly as much as some of you. I would absolutely pay more for a gun, and I HAVE paid more then going value for guns that the previous owner has provided me with an accuracy guarantee. So far the only lemons I’ve purchased have been new guns, not used.
