FX Pantera question

Are you aware of that if you take the "item" out of dealers doors, that item not new any longer. Especially you opened the box it won't be new. And if somebody paint you as a google mechanic, you lost a great chunk of cash right there.
Me personally I would not buy any second hand AG unless the cost worth a bag of peanuts.

Shot or not it's still considered used you'll lose some on it if it were me I'd just shoot it the 30 Cals are accurate

A PRS gun is a heavy bench rest tool. The Pantera is not exactly a lightweight hunting friendly rifle anyways. I would expect about 60% tops and probably less unless you just hit the right person. And then there is shipping which can be considerable with potential damage as happened to me not long ago. Maybe it is time to take up bench rest?

PBs can increase in value if well cared for, even many times over, patina can even add to value. I doubt many air guns hold any intrinsic value. The models change too frequently, new gizmos, yesterday's hotness is tomorrow's old busted down antique. Old and antiquity befits a PB, airguns, no. That is why I own expensive PBs less expensive air rifles.
