Bought a new 2x7 bdc viper. Seems to be a nice scope except that it has what I can only think to describe as 2 blisters or bubbles toward the bottom right when looking through it. Great glass Holds Zero and tracks, just annoying to see that. I Really hear a lot of good thing about vortex, so I'm Just wondering has any on else had this issue. Could just be a weird defect on just this one. Just wondering.
