I like the Leapers UTG Max Strength Picatinny Rings in medium height. I have several of these on my Taipans, Kalibrguns, and Vulcans. From reading several other posts on here about what rings most other Taipan owners find a best fit it would have to be medium height rings. This works well for the 30mm tubes and 50mm objectives and maybe larger like 56mm. Optics Planet has a 10% off sale right now too that I took advantage of for other items.
