Description

The Holosun HM3X Brown 3X Magnifier is a versatile, high-quality optical magnifier designed to extend the capabilities of your favorite red dot sight. Featuring a distinctive Brown finish, 3X optical magnification, and an included flip-to-side quick-detach mount, the HM3X-BRN offers an excellent combination of optical performance, durability, and affordability.

The Holosun HM3X features an adjustable diopter that allows users to fine-tune the focus for a crisp, clear sight picture. With a generous 2.75 inches of eye relief and a wide 7-degree field of view, this magnifier delivers comfortable viewing and improved visibility at longer distances.

One of the biggest advantages of the HM3X is its included flip-to-side quick-detach (QD) mount, which allows users to quickly transition between 1X and 3X viewing without removing the magnifier. The included spacer provides compatibility with both absolute and lower 1/3 co-witness height red dot setups, making it an excellent addition to a wide variety of optical configurations.

Built with a rugged aluminum housing, nitrogen-purged optics, and an IP67 waterproof rating, the Holosun HM3X is engineered to deliver dependable performance in demanding environments.

  • Wide Field of View: Features a 7-degree field of view for excellent visibility through the magnifier.
  • Durable Aluminum Housing: Rugged construction designed for long-lasting performance.
  • IP67 Waterproof Rating: Sealed design provides protection against dust and water exposure.
