Will your cheap airguns be able to shoot out to 75 yards? Do you need a 10 yard parallax?-Y
IMO a cheap scope is the ultimate waste of money.
This one. Not great, but not bad, either. Around $50 to fit your budget.https://winchesterairrifles.com/product/2-7x32-rifle-scope-ao/On Amazon this is $49. For some reason, I can't post the Amazon link.

I would look into CenterPoint scopes. I have a 4-16X that is a really, REALLY fine scope. I guarantee if you could use it you would be amazed at how well it works, tracking is great and the only real downside is it is a bit dark at 16X, and the reticle is a bit thick. Neither of these complaints are anything to get excited about, as they are minor, not deal breakers. I've seen worse scopes at more than twice the price. I'm sure CP makes lower mag scopes that would work. Also, the Hawke Vantage 4X is good. You can find several Simmons 4X scopes on ebay too. If you go 3-9X, then there's a ton of them around. UTG if you get a good one, is pretty decent, but hit or miss. Hawke Vantage 3-9X is good. Lots of cheap scopes that work well without breaking the bank.Believe me, I've been where you are now and looked through a lot of scopes. Good luck
