What's your budget? Recommendations will vary based upon that
My 17HMR had a Sig Tango 4 4-16x FFP for longer range daytime target/prairie dog shooting. I'm now switching to a Sightron S-Tac 3-16x42 SFP.
Although the Droptine is decent, it has some obvious drawbacks. FOV is limited and I find the eye relief less than ideal but that's less critical on a rimfire. Also, although the minimum 50 yard parallax is usable, if you can afford something that goes down to 35 or 10 yards you will be better off.
If you can swing the S-Tac, I'd recommend it:
