For scopes I would go with MILS. In marksmen class you are limited to using up to 10 power. The scope can go more but you just cant use it past 10. A reticle with holdovers or MIL markings is ideal and something with a christmas tree will be come more useful to.
Something in the 4-16 range is a good starting point, Element titan or Helix, Arken are a few
