Holosun HM3X 3x Magnifier with Flip QD Mount

Holosun HM3X 3x Magnifier

The Holosun HM3X is a 3x magnifier designed to pair with a red dot or other non-magnified optic to provide a temporary magnified sight picture. It mounts via a quick-detach, flip-to-side Picatinny mount and offers adjustable focus and zeroing controls for precision alignment with a primary optic.

Core Description

The HM3X converts an unmagnified sight into a 3x optical setup for clearer target identification and more precise sighting at extended distances. It is intended for use with compatible red dot or reflex optics where an auxiliary, quickly-deployed magnifier is desired—examples include range use, duty or patrol setups, and other primary-optic-with-magnifier configurations.
