Hi all, I am trying to get some advice from you all on a new scope for an AR 15. Main uses will be hunting and Target shooting under 500 yards. I have looked at the Leupold mark are mod 1 3-9x40 and vortex diamondback tactical 3-9x40. My budget is under $500. Any experience with either of these scopes or other recommendations. Any info helps thank you all and God bless.
