      Good magnifier

      Good magnifier and flip to the side mount

      Thank you for the feedback, Stephen. We're glad you're satisfied with your new magnifier! -- LM
      Very Pleased

      I was a little hesitant about buying an open box item such as this but the magnifier was in like new condition and works great. The magnifier itself is very well designed and constructed. I had a few questions about adjusting the mount which were answered very quickly by AT3 support. The magnifier sits behind an RD-50 which I am equally pleased with.
