🔍 Key Features & Benefits

Exceptional Low-Light Clarity

The 56mm objective lens gathers ample light for superior visibility during early dawn and late dusk — the prime hours for hunting. Multi-coated lenses enhance contrast and reduce glare, providing clear target acquisition even in challenging light conditions.

Illuminated Red HDR Reticle

The HDR (Holdover Duplex Reticle) offers illuminated red center crosshairs for fast aiming in low light and precise shot placement at distance. Adjustable illumination settings allow you to tailor brightness intensity to ambient lighting conditions, helping maintain visibility without overpowering your natural sight picture.

Wide Magnification Range: 3–12x

The 3–12x variable zoom gives shooters the flexibility to engage at close, medium, and long ranges without losing field awareness. Smooth magnification adjustment enables quick transitions — ideal for hunters who might spot and engage targets across variable distances in a single outing.

30mm Main Tube

The larger 30mm aircraft-grade aluminum tube enhances light transmission, supports greater internal adjustment range for elevation/windage, and increases durability. It’s shockproof, fogproof, and nitrogen-purged to handle recoil from high-powered rifles and resist fogging in changing weather.

Rugged Hardcoat Anodized Finish

The black hardcoat anodized body protects against scratches, moisture, and corrosion. Built for harsh hunting environments, this finish ensures the scope retains its tactical appearance and dependable function season after season.
