Hi all. I'm not new to firearms, but have largely shot handguns and milsurp rifles to this point. I really don't know anything about optics, but have recently purchased a couple rifles I'm going to want them for. Care to point a guy in the direction of an "optics for dummies" website? Thanks... FYI - I'll be looking to get optics for a CZ Scorpion Evo & a CZ Bren 805. Thanks again!
