That’s a tough one.
If I gauge that by accuracy I would have to say my Streamline but that’s not a cheap rifle.
If I go by price then I’d have to say the Beeman P17 since it’s one of those great values out there if not THE greatest value.
If I value stealth as my top priority I would have to vote the Wildcat since it’s both compact and quiet with a moderator mounted. I would also have to give the WC the nod if I based my best purchase off of which one gets the most use.
If I were to go off looks and pride in ownership I would give the title to the Royale 400 in gray laminate.
If my best purchase was based off of something that I actually put my time and effort into to turn a sows ear into a silk purse I would give that crown to the QB78 that I converted to air, a repeater, custom made stock and LW barrel.
But if I were to combine all of those attributes together and a little more, I would have to say my best purchase was a HW95 .177 caliber from AoA when they were offering them for $299 a handful of years ago. It does everything I need, fits great, quality build, accurate, not loud, simple beauty, pride of ownership, easy to operate and maintain.....
