Holosun HM3X 3X Magnifier with Flip-to-Side QD Mount
The Holosun HM3X is a fixed 3x magnifier built to pair behind red dot optics, adding magnification without changing your primary sight. It features a flip-to-side quick-detach mount for fast transitions between 1x and magnified viewing.
Rugged aluminum construction with a black MAO finish, nitrogen-purged internals, and IPX67-rated sealing make it well-suited for hard use. The HM3X offers a 7° field of view, 70mm eye relief, and a ±3D diopter adjustment to fine-tune focus.
