Discovery HT 4 16x40 SF

The Discovery HT 4-16X40 SF is a high-performance rifle scope designed for hunters, sport shooters, and outdoor enthusiasts who need clarity, reliability, and consistent precision across a wide range of shooting distances. With its 4x to 16x magnification range and 40mm objective lens, this scope delivers both the close-range flexibility and long-range detail needed for versatile field use. The integrated Side Focus (SF) mechanism adds even more accuracy to your shots by correcting parallax from close distances to infinity. Ruggedly built and optically refined, the HT 4-16X40 SF is an ideal scope for shooters who need dependable performance in the field or at the range without overcomplicating their setup.

The 4x to 16x magnification offers the flexibility needed for different types of shooting scenarios—whether you’re scanning a game trail at 100 yards or targeting distant silhouettes at 400+ meters. At the low end, 4x provides a wider field of view for fast-moving or close-range targets. Crank it up to 16x, and you’ll have the precision needed for long-range accuracy, target identification, and tight groupings. This makes it ideal for hunters, competition shooters, and tactical users who value clear performance across varying distances.

The 40mm objective lens hits the sweet spot between light-gathering ability and compact profile. It provides enough brightness and clarity for early morning hunts and late evening shots, while maintaining a slim and lightweight feel ideal for portable setups. The lens also ensures excellent edge-to-edge sharpness and natural color rendering, giving you a more detailed view of your environment. Whether you’re in shaded forests or open fields, your visuals remain crisp and immersive.

One of the standout features of this scope is its side focus (SF) parallax adjustment. Unlike fixed parallax scopes, this one allows you to fine-tune focus and eliminate aiming errors at any distance, from short-range targets to distant marks. Located conveniently on the side turret, it lets you dial in clarity without shifting your shooting position. This is especially useful when shooting from a benchrest or prone, where maintaining eye alignment is crucial for long-distance accuracy.

All air-to-glass surfaces on the HT 4-16X40 SF are treated with full multi-coatings that enhance light transmission, reduce glare, and improve image contrast. This optical treatment ensures brighter images, especially under low-light conditions like dawn or dusk. You’ll experience less eye fatigue and better target discrimination, even at higher magnifications. These coatings also improve overall durability by protecting lens surfaces from scratches and environmental wear.

The scope body is built from a solid piece of aircraft-grade aluminum, making it resistant to recoil, shock, and tough field conditions. It’s nitrogen-filled and O-ring sealed, providing waterproof and fogproof performance in changing weather. Whether you’re hunting in rainy forests, dusty plains, or dewy early mornings, this scope holds its zero and clarity. Its black matte finish also helps reduce reflections, keeping you concealed in hunting or tactical environments.

The scope features low-profile turrets for windage and elevation adjustments, each offering audible and tactile clicks for quick dialing. These turrets make it easy to zero in your rifle and adjust on the fly for wind drift or bullet drop. The clicks are clean and consistent, ensuring you can track your changes without over-correcting. Once zeroed, the scope holds firmly in place, even through extended recoil cycles or repeated handling.

This scope provides generous eye relief, allowing for safe use with high-recoil rifles while also being more forgiving in your shooting position. The wide eye box ensures a quick and easy sight picture without having to fine-tune your eye alignment every time. Whether you’re adjusting for elevation or engaging multiple targets, the consistent eye relief allows for a smoother shooting experience with less fatigue during long sessions.
