I've been reading about the Eotech 512. Some swear by it, yet others chose the Aimpoint. What model Aimpoint would be comparable with the Eotech 512? Any suggestions for this type of sight for less money? My purposes would be for quick, accurate, sight access from close range (HD) out to 100 yds. (range) Maybe some of you Optics Experts could chime in here. Best red dot or quick sight for the money? Thanks in advance.
