Holosun HM3XT Titanium 3X Magnifier

The Holosun HM3XT is a compact 3X magnifier built to extend the capability of a red dot or reflex sight without replacing its close-range speed. Its Grade 5 titanium housing, ambidextrous flip-to-side mount, and quick-detach Picatinny interface create a durable magnification system for defensive carbines, duty-style rifles, competition platforms, and general-purpose range builds.

Fixed 3X magnification improves target identification and provides a more detailed sight picture at intermediate distances. When magnification is not needed, the HM3XT pivots to the side so the primary optic can be used normally at 1X. The ambidextrous mechanism supports rapid transitions from either side of the rifle.

The shortened titanium body reduces the amount of rail space required behind the primary optic while providing exceptional resistance to impact and hard use. Compared with a conventional aluminum magnifier, the Grade 5 titanium housing delivers premium material strength in a compact optic designed to withstand demanding rifle and carbine applications.

Holosun equips the HM3XT with optical-quality glass and multi-coated lenses to promote clarity, light transmission, and reduced glare. Its 6.6-degree field of view supports target tracking and situational awareness while magnified, while approximately 65mm of eye relief allows a practical head position behind the optic.

Integrated windage and elevation adjustments allow the magnifier’s optical center to be aligned with the reticle of the primary sight. These controls do not change the firearm’s zero; they simply center the viewed reticle within the magnifier’s field of view.

The included quick-detach mount supports both absolute and lower 1/3 co-witness optic heights. Install the supplied spacer for a 1.63-inch lower 1/3 centerline or remove it for a 1.41-inch absolute co-witness configuration. This allows the HM3XT to pair with a wide range of Holosun and similarly mounted rifle optics.

Sealed and nitrogen purged to resist internal fogging, the HM3XT carries an IP67 environmental rating and a 1,000G vibration rating. Its combination of titanium construction, compact dimensions, adjustable mounting height, and instant flip-to-side operation makes it a premium solution for adding mid-range capability to a red dot-equipped rifle.
