I hope and think yours should be ok,, I got a 512.a65 3 days ago, I went to the range to zero it in and it did look fuzzy to me,, I just thought it was normal,, Second day got it perfectly zero'd at 30 yards and was shooting nice groups but still looked fuzzy, today I went and really focused on the two eye open concentrate on target thing,, and it became incredibly sharp, i was wierded out because I though somthing had happened,, but I turned the brightness down a litle ( indoor range ) and just tried to focus on the paper and the 1 moa dot looked like a laser beam.
Ive never shot such tight groups since I got this baby, they really are great,, and target accuqsistion is amazing,, 20 fairly rapid fire shots with a super tight gruop in the target area,, im a total newb and it makes me look alot better than i should be.
now i gotta get a acog!!
