This is by far Sightmark's most powerful, long range riflescope. Engage targets further away then ever, all while maintaining a great amount of clarity and light transmission. Red and green illumination of the center aiming dot available as well.


Sightmark now features award winning riflescopes with Mil-Dot Dot reticles. These riflescopes include a complete mil-dot black crosshair with an illuminated red or green center dot only. Having only the dot illuminated, rather than the entire reticle, allows the shooter to view more of the target, not just the reticle. The Mil-Dot Dot reticle also emits less illumination, eliminating distortion of the target. 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 in 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. The Triple Duty series of riflescopes are complementary to any shooter's arsenal.
