There are very nice Athlon options... Talos BTR at $610 is the entry point... the Argos BTR 6-24 is $720 and a really nice scope... These 2 lean on older scope specs... still very functional and will work fine.
The Ares BTR which I used is $1375...
from there you can look at the Ares ETR, Cronus BTR, Delta Strykers... all are 34mm scopes, better glass and more scope travel.
The Ares BTR has all the features you would want in a PRS type scope... very nice optics for the price point and tracking has been solid for me. From there, you are adding scope travel and better glass... and that better glass only really matters if aiming at itty bitty targets at long range. if you have the budget, these 34mm scopes are very nice.
