      Magnifier + Red Dot

      I received my order fast. Great and friendly customer service they answered all my questions. The magnifier and red dot mounted together easy. The magnifier can be mounted right or left handed. Can't wait to try them out.


      I had ordered the red dot sight and riser when the Magnifier was sold out and was given the set price when I purchased it which was great. It was exactly what it was advertised to be and I am very happy with the purchase. Cant beat the free shipping and the shipping time was super. I will be shopping there again.

      Thank you, Scott. We appreciate the feedback, and we're glad you're liking the magnifier
      Nice Magnifier!

      Just like the RD-50, this is a well-constructed optic especially considering the price point. Easy to install and adjust. Operation is great. The only downside for me is the eye relief but that is easily overcome with use.

      Robert, thanks for the orders, and we're glad to liked the magnifier!
