Confused by SRAM Rival Chainring replacement options

I'd like to replace the chainrings on my 50/34 110 SRAM Rival OCT Crankset.

What I have looks like this: where the outer ring looks less "spidery" than most of the 50T replacement products I'm finding.

thougts?

You have a OCT crank and chainring and the ebay one is not OCT.

"OCT" has nothing to do with chainring compatibility. OCT (Open Core Technology) is the crankarm design. In your case the important number is 110 bolt circle diameter (BCD). Rival cranks will accept many different rings of the same BCD. Personally I replace the rings with Shimanos on all SRAM cranks. I feel Shimano has improved shift feel.
