I went with these: https://www.amazon.com/gp/product/B003GSOKDG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

But I'd say, do your own research. Height depends on your scope, you have to have clearance depending on how bit it is, and it's also preference on how high you want it I believe.

Honestly, I swear I spent more than 16 dollars on these when I bought them, so I may have ended up using a different set.

I couldn't find vortex brand rings on Pyramydair, so I'm back looking on amazon for the rings. There were a few different price ranges, but I wasn't sure about the differences. Do these look okay? Vortex Optics Hunter Riflescope Rings (1 inch - Medium)

Also, I think I'll start with a pump and see for myself why a compressor is a good idea! Is this the pump/pump kit you recommended? The kit appears to come with QD and filter, which I assume is a good idea to get. I just wanted to make sure it's compatible with the field and target since it's Air Venturi brand.

Lastly (I hope), the pellets you recommended seem to be out of stock on Pyramydair. Do you recommend any other pellets for the field and target, until they are back in stock? Thank you so much!
