As others have noted, the price paid for an optic should not be related to the cartridge being fired. But the specifications should. I'd say that the optic that the OP has for sale isn't really a good match for the .22LR. But for an interim period (i.e. until someone makes and offer on it) using it on the .22 in the 6x-12x range would work just fine.
I have a 2-8 BDC Nikon on my AR-styled .22LR and just bought a 2-7 Nikon with BDC for a new 10/22 that I just purchased. They seem like a good match for me for the .22LR though I wouldn't mind have more magnification if I didn't have to spend so much money to keep the low end remain around 2x. Nothing but a simple application of money but I'll hold off for a while on that.
To the OP, shooting .22's is one of the more enjoyable parts of the hobby so being well equipped for that endeavor is a wise path to take.
