I narrowed down to a type based on the division I plan to shoot in, so a 1-4 ish power scope is great.
Do you have any freaking idea how many 1-4ish power scopes are out there? Reticle choices, price, who makes good glass, who doesn't, who has good customer service, who doesn't, Mil-dot or MOA.....
And then once you finally decide on the glass you need a mount for it which is a whole other series of choices.
The best part is that it isn't uncommon to have an optic which costs more than the rifle it is mounted on.
I've finally figured it all out for my own uses, but damn....that's only taken a few months of research and I still have to work on Mil-dot calculations for hold overs and range estimation.
