New HM3X Red Dot Magnifier from Holosun

    Holosun is introducing a new line of red dot magnifiers, called the HM3X line.

    One could suspect that being short for “Holosun Magnifier with 3 times magnification“.

    The magnifiers will allow the shooter to transition between an unmagnified red dot to three times magnification.

    The Holosun HM3X housing is IP67 Certified and made out of aluminum. The design is “Flip to the Side” and the lens has an adjustable diopter so the user can achieve the correct focus.

    The Holosun magnifier has various solutions depending on how you want to mount your magnifier. The QD Mount and Spacer is included in the package and is compatible with absolute cowitness and lower 1/3 Height Optics.

    From the Press Announcement, with more details:

    Holosun Introduces New HM3X Magnifier

    City of Industry, CA – Holosun is pleased to announce the release of their 3 power Flip-to-the-Side Magnifier, the Holosun HM3X. This new product debuted to the public at the NSSF SHOT Show 2019 to much industry acclaim.

    The clear glass and very generous 2.75″ eye relief of the HM3X are designed to pair with and augment Holosun’s red dot lineup.

    With its flip-to-the-side design, the HM3X allows users to toggle between an un-magnified and 3 power magnification view through their optic as situational requirements demand.

    The HM3X’s aluminum body is durable and corrosion resistant, protecting it from the wear and tear of heavy use.

    The IP67 water and dust tight rating combined with a nitrogen gas purge ensure that the HM3X won’t let you down in humid or damp environments.

    Holosun offers versatility and value in all its offerings, and this magnifier is no different. The unit includes a quick detach mount that can be rotated during magnifier installation to allow it to flip either to the right or the left.

    Additionally, the mount has hard stop positions that sit straight behind an absolute co-witness height optic (1.4″ from the top of the rail to the center of the lens) or flipped-to-the-side at ninety degrees. Also included is a spacer that creates compatibility forlower 1/3 co-witness height optics (1.63″ from the top of the rail to the center of the lens).

    The price? The debut MSRP is $235.28 and it will be available through either Holosun’s online store, Davidsons Gallery of Guns or at other authorized retailers.
