This has a 3/8 dovetail Rail so this could take just about any type of scope. You can buy dovetail scope rings or buy a dovetail picatinny rail so you can use picatinny scope rings. Hope this helps.

The Mounts are 3/8" so any scope with 3/8" clamps will work. There are many types of scopes available. I guess it all comes down to purpose (Plinking or Hunting) & how much you'd like to spend?

Scope, it has a receiver grooved ⅜" dovetail. An excellent and ready to mount scope is here : amazon.com/Hammers-Riflescope-3-9x40-Plinker-Dovetail/dp/B003UNS9H0

It has ⅜" dovetail mount, so it'll take any scope rings that attach via ⅜ dovetail, or you can get a dovetail to picrail, or dovetail to weaver rail mount, and then you can mount any scope/optic that attaches to a pic/weaver rail.
Buds has an assortment of ⅜ mounts here are rings and rail adapters, irons, whole scope kits etc.

For 22LR I prefer a good entry level reddot on a pic rail.

That's pretty much the exact setup I have on my 22lr. But with the products in my 1st link you can set it up how you like.
