Sightmark Triple Duty 10-40x56 Sight Riflescope Illuminated (SM13018)






The Sightmark Triple Duty Riflescope is equipped with an illuminated red/green Mil-Dot reticle, which aids in range estimation and shooting in low light conditions. The Sightmark 10-40x56 Triple Duty Riflescope uses cutting edge glass with fully multi-coated optics, increasing clarity and making it one of the best riflescopes on the market. The fully multi-coated optics transmit a bright and crisp picture that makes tracking and shooting targets quick and easy. The 10-40x56 features a one-piece 30mm tube that increases light transmission and field of view. O-ring sealed and nitrogen purged, the 10-40x56 is both fog proof and water resistant. This precision scope features a parallax adjustment knob and oversized, locking windage and elevation turrets with 1/8” MOA clicks, making difficult long range shots more accurate.
