The ideal magnifier should be lightweight, durable, and user-friendly. The Sightmark XTM 3 magnifier is a prime example of an optic that fulfills all three criteria.
When compared to its closest rivals, the XTM 3 is more than an ounce lighter while providing the same magnification power. It offers a comparable angular field of view and IPX7 waterproof rating to its counterpart, all at a more affordable price point than the closest comparable model. Notably, the Sightmark XTM 3 distinguishes itself with a more ergonomic flip-to-side mechanism, setting it apart from the push-press flip of rival models. The Sightmark XTM-3 magnifier excels as an exemplary optic that embodies the essential qualities of a great lightweight magnifier.
When you need to transition from close-range engagement to mid-range precision shots without adding extra weight to your rifle, the XTM-3 Magnifier is the right tool for you. Sightmark offers the lightest, most compact magnifier in the market today. Weighing only 8.1 oz, this 3-inch long magnifier has an 18mm objective lens and provides 3x magnification to a wide variety of rifle-mounted red dot sights.
Outfitted with a no-nonsense flip-to-side mechanism as well as a simple locking quick detach mount, the XTM-3 is designed with practicality and ergonomics in mind. Constructed with shockproof 6061 aluminum housing with an IPX7 waterproof rating and a nitrogen-filled chamber to eliminate fog, the XTM-3 Magnifier is a quality magnifier that’s built to last.
