I got my vortex viper 6-20x50 this past week and when i took it out of the box i was impressed. Nice fit and finish. I really like the fast zeroing function of the turrets (crafty!!) . I took it to the range today for the first time. The eye relief was a bit disappointing. Way to close for my likings at the upper ranges of power. Glass is nice, but i am pretty sure it wasnt crisp from edge to edge. It seemed to me that the edges were a bit fuzzy, again on the upper ranges of power. I will need to take it out again to confirm that i wasnt seeing anything in the near surroundings causing the fuzzy edges. Parallax worked well and the scope held a good zero. I got the BDC model for long range hunting and i like the MOA distance between dots for my rifles load. A 100 yard zero with my 6x47L is the cross hairs. First dot below is 250 yards and the second dot will hit at 400 yards. that is great for my intentions. Over all pretty good, the close eye relief has be a bit bothered though. Has anyone else experienced fuzzy edges and a close eye relief problem? If the rifle were any bigger than a 6x47L i might have a black eye. Keep in mind i am not optic expert, and i only got to spend about 45min with the scope so far. I will report more tomorrow if the weather holds. I also took out my new Sightron s3 and that scope rocks!!!!! Lee
