I am loking to try some F class comps this year and want some new glass. I have a 4x16 Primary Arms on it right now. I think my max yardage will be 600 yards. Whats my best bang for the buck at $500 or less? I need ideas and help withthis as i have never spent anywhere close to this much on a scope and there are so many to choose from. Everything else on my build is complete and this is where I am lacking. I have been looking at Vortex. Whats your thoughts? Thanks
