Its variable magnification spans an impressive 5x to 30x, providing versatility from moderate distances to extreme ranges. This wide range is accommodated by a robust 34mm tube, which offers greater internal adjustment travel compared to the more common 30mm tubes.

The 56mm objective lens is a key component for light gathering, ensuring a bright and clear image even in low-light conditions. The Second Focal Plane (SFP) reticle, a Mil-based design where every quarter Mil is clearly marked, remains consistent in size relative to the image, which is preferred by many for consistent ranging at specific magnifications. For reticle ranging, this design means the subtensions are accurate only at the highest magnification (30x in this case).

The scope features a patented ballistic elevation turret with six colored markers, allowing shooters to pre-set up to six different ballistic hold points for quick reference. This system requires the user to know their rifle’s specific DOPE (Data Of Previous Engagement). Elevation and windage adjustments are precise, with a click value of 0.1 Mil Rad, and a total adjustment range of 85 MOA (which translates to approximately 25 Mil) in both directions. The turret adjustment type is listed as MOA, which seems to be a slight inconsistency with the click value being in Mil Rad; typically, the adjustment type matches the click value.

Optical coatings are extensive, featuring DiamondTuff14 and being fully multi-coated to maximize light transmission and reduce glare. The HD Low Dispersion glass enhances clarity and color accuracy, crucial for target identification at distance. Eye relief is a comfortable 3.3 inches, which is adequate for most magnum calibers.

For illumination, the reticle features an LED illumination system powered by a single CR2032 battery, offering 11 brightness settings and a claimed battery life of 300 hours. Parallax adjustment is adjustable from 10 meters to infinity, allowing for sharp focus at any range. The scope is constructed from durable aluminum and is nitrogen-purged and sealed with rubber gaskets for fogproof and waterproof performance, rated to IP67 submersion up to 1 meter. The overall weight is 32 oz, and the length is 14.6 inches, reflecting its robust construction and large objective lens.
