Questions & Answers
What flip to the side mounts will for this magnifier? Manufacturer Answer

This magnifier's body size is 30mm. Most shooter's utilize magnifier's in combination with a primary optic such as a red dot or 1x prism. If this combination set-up is your intended use then you will need to know the central height of the primary optic and find a flip-mount that place the magnifier at the same central height.

Will this work with the Unity Tactical flip to center magnifier mount? Expert Answer

Pull the trigger and get it by Jsle, Verified Owner, March 6, 2019

Great Eye Relief by Eric, Verified Owner, May 23, 2023

This little magnifier rocks by Kbada, June 21, 2018
Built like a tank, great eye releif and super clear glass. Would highly recommend this to anyone. Optics planet did a great job packaging and shipping quickly and you can’t go wrong with their return policy as well as primary arma warranty terms

Good Buy, Great Optic. by phred, February 8, 2018
I tried the 6x magnifier first, it's too much magnification to shoot free hand at any range, every movement leads to another overcorrection, only 50% hit rate at 50 yard 8" steel, 100 % without magnifier, it has to be braced to be effective at any ra...
