Quickly increase your target size and accuracy with a Holosun HM3X Magnifier. Holosun is proud to introduce the best magnifier value on the market today. The HM3X line of magnifiers will allow the operator to seamlessly transition from unmagnified to 3X magnification and features an adjustable diopter to dial in the desired focus. Featuring extremely clear glass and very generous eye relief. The durable aluminum body uses extremely clear glass but also an adjustable diopter and generous eye relief to give you the confidence on shots beyond the range of a reflex sight. An integrated QD mount uses a flip-to-the-side design and includes a spacer for absolute co-witness and lower 1/3 co-witness so you can seamlessly transfer from an open sight to 3x magnification.

Since 2013, Holosun has been committed to creating innovative optic and laser/IR technologies for a broad range of shooting and hunting needs. Today, Holosun is at the forefront of developing because of new features and innovations such as a 100,000 hour battery life, Solar Fail-Safe technology, Our signature multi-reticle system (MRS), and much more. At Holosun, we are obsessed with producing cutting-edge equipment with superior quality but at a price that astounds the competition and the customer. Here at T and K Outdoors we stock all of Holosun’s products because why not. The red color is the most common but people say green is the easiest to see.
