Sightmark XTM-3

Sightmark is unveiling the XTM-3, a flip-to-the-side 3X optical magnifier. The new Sightmark XTM-3 also holds the distinction of being both the smallest and lightest magnifier currently available on the market, with a weight of approximately 8 ounces and an overall length of 2.72 inches. The magnifier comes with a true flip-to-side mechanism and has a waterproof rating of IPX7. Most importantly, the new Sightmark XTM-3 Magnifier is compatible with most red-dot or reflex sights available on the market today. Magnifiers are generally paired with red dot sights in order to provide a moderate magnification capability in order to facilitate extended shots at further distances, as those types of sights typically provide no magnification.

Sightmark designed this new magnifier for convenience on all fronts. The optic comes with a tool-less quick detachable mount for use with any Picatinny rail system. Likewise, the unit can have both its windage and elevation dials adjusted by hand without the use of any additional tools. For shooting convenience, the new Sightmark XTM-3 has an eye relief of 2.32 inches for easy positioning on your firearm of choice.
