Both of those scopes are going to be a bit big for the rifle, I'd say go to the 5 over the 7 since it will fit the rifle a bit betterI also really like the looks of the Prostaff 3 EFR target, specs out as almost the perfect combo for a offhand target rimfire rifle, I may check out one for my 10/22 I use for hunting, I'm just worried the reticle maybe to fine. Also check out the Vortex Diamondback and Crossfire II rimfire editions. Maybe even check out the Leupold VX-Freedom EFR 3-9X33 or if you can find a VX1 rimfire that would also be an excellent choice.
