My son-in-law has just picked up a Ruger American. It is in 308 and he's wanting to do some deer hunting with us this fall. I would like to buy him an entry-level scope but don't really know what that market looks like right now. I've seen companies like Athlon, Hawke, Riton etc. But I just don't know what this entry level market really offers these days. Any recommendations? I'm thinking something simple like a 3–9x40.
