I found a nicely-figured, slightly used one in .22 WMR and decided to not get the other barrels because I have other .22 LRs and don't want to shoot the .17.
If I had more than one barrel, I'd consider having a different scope to be used for each barrel, sighted-in to best match the trajectory of the cartridge. That way, it's more likely that a person wouldn't need to sight in the rifle each time the barrel is swapped. (Label each scope, to keep them straight.)
The rifle is nice, but mine needed to have a few "tweaks" to shoot 1" groups at 100 yards. It's finicky on ammo choice also, preferring CCI V-Max, 30 grain rounds. A few other brands/types shot well, but nowhere near the same POI.
