The TrijiconA(R) MGRS(TM) Machine Gun Sight with 3X Magnifier is specifically designed for use with LMGs, offering quick target acquisition and accurate shot placement under heavy and consistent recoil. Featuring a large field of view and a powerful LED-illuminated reticle, the MGRS greatly enhances first-round hit probability, significantly reduces target acquisition time and ammo expenditure, and maximizes accuracy in high-volume fire scenarios. The 7075-T6 aluminum housing easily withstands heavy use and abuse in extreme environments. The corrosion-resistant Mil-Spec anodized finish protects against rust and corrosion from wet, dusty, or sandy conditions. Two interchangeable dials, calibrated for use with the M2 (.50 caliber) and M240 (.308/7.62) machine gun, allow you to dial in target distances for superior accuracy and consistency with specific weapon platforms. The 35 MOA segmented circle with 3 MOA dot reticle significantly increases the probability of first-round hits, while 7 user-selectable brightness settings (2 night vision, 5 daylight) offer intuitive target acquisition in any lighting condition. Three detachable Picatinny rails accept a variety of lasers, rangefinders, and other accessories to the top or side of the optic, and the built-in flip-up 3X magnifier allows you to transition between CQB and intermediate-ranged targets with ease. Plus, fully multi-coated, broadband, anti-reflective glass lenses maximize light transmission and maximum color fidelity, and the optics are nitrogen-filled and fog-resistant for superior edge-to-edge clarity. Includes integrated Picatinny-compatible mount. Operates on one CR123 battery (included). Submersible up to 6.6' (2 meters). Drop, vibration, and immersion tested.
