Vortex Optics designed and built the 4-16x44 Diamondback Tactical Riflescope to meet the needs of tactical professionals, but with easy usability for hunters. Its low-to-moderate zoom range makes it ideal for mid-range use, with the ability to reach out to longer ranges if needed. This model has a 44mm objective, which gives it better light-gathering ability compared with the smaller models but without the bulk and weight of the larger long-range 50mm versions. Extra-low dispersion XD glass and anti-reflection fully multi-coated optical surfaces complement the magnification range and objective by transmitting bright and clear high-contrast views with accurate color and improved edge-to-edge contrast and resolution.
The scope is based on the MRAD scale, with exposed tactical finger-adjustable turrets for fast impact point correction in the field. Windage and elevation adjustments are made at 0.1 MRAD per click with 6 MRAD travel per rotation and a broad 25 MRAD range available. The tactical EBR-2C reticle, placed on the first focal plane, maintains its subtensions at all magnifications to make corrections without having to touch the turrets or to estimate the range to and size of your targets. The scope is parallax free to 20 yards, with a side adjustment correction turret for distances from 20 yards to infinity.
Its sturdy 30mm one-piece maintube provides a solid platform for the internal mechanisms and is made of a lightweight and durable aluminum alloy that has been treated with a scratch-resistant low-reflectivity matte black anodized finish. To withstand the rigors of heavy outdoor use in all weather conditions, the optical tube is nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging.
