I've got a pst, sightron s3, elite 6500 t and a night force. no offence to you, but i'm starting to wonder if some individuals who are implying that the vortex and sightron are comparable to nightforce, are doing so because That's all they sell. there is a night and day difference between the vortex and night force, if you want an opinion from a retailer who carries and has field tested all three lines, talk to the team at atrs. also, from what i've been told, the profit margins on the night force are very small when compared to the other two brands.
