Discovery Optics VT-R 4-16x42 AOAC

• 4-16x magnification range: Covers the gap between short-to-medium stalking distances and more deliberate shooting from a rest, so one riflescope can handle varied field conditions without feeling over-specialized.
• 42 mm objective with fully multicoated optics: Helps maintain a bright, usable sight picture and better contrast in mixed light, which matters when targets stand against dark backgrounds or shaded cover.
• Side-focus parallax adjustment: Lets the shooter fine-tune image focus from 9.14 m to inf. without changing position, making precise aiming easier at both airgun and centerfire distances.
• Tactical turrets with 40 MOA adjustment range: Provide direct, repeatable correction for elevation and windage, useful for range work, hold verification, and rifles that need more adjustment flexibility.
• Nitrogen-filled, waterproof, fogproof and shockproof construction: Supports reliable use in changing weather and rough handling, reducing the chance of internal fogging or loss of zero during regular field use.

About the Discovery Optics VT-R Series

Discovery Optics VT-R is the brand’s entry-level riflescope series, built to give shooters a practical mix of variable magnification, straightforward controls, and field-ready durability without moving into heavier specialist designs. The range was presented with several configurations, including 3-9x40AC, 3-9x40IRAC, 3-12x42AOAC, 4-16x42AOAC, 6-24x42AOAC, and 10-40x50SF, which shows how the series is intended to cover everything from general hunting use to target practice and informal long-range work.

Within the VT-R family, Discovery Optics uses VCF fully multicoated optics and its TES erector support system to balance image quality with mechanical stability. Adjustable-objective variants in the series are designed for parallax correction from 10 yards to infinity, which makes the line especially relevant for shooters who move between short airgun distances and longer centerfire ranges. The VT-R models shown in the catalog use a 1-inch tube, keeping the scopes trim and easy to mount on a wide variety of hunting and training rifles.

About the Discovery Optics VT-R 4-16x42 AOAC

Discovery Optics VT-R 4-16x42 AOAC is a variable-power riflescope aimed at shooters who need more reach than a basic stalking optic but still want a compact, manageable setup. Its 4-16x magnification range gives enough low-end power for general field use while extending high enough for careful shot placement on small targets, load development, and range sessions where target detail matters. Paired with a 42.00 mm objective, the scope keeps overall size under control while still gathering enough light for practical daytime hunting and training use.

A key part of this model’s usefulness is its side-focus parallax adjustment, which works from 9.14 m to inf.. That makes the scope more versatile than a fixed-parallax design, especially for air rifles, rimfires, and centerfire rifles used across very different distances. Correcting parallax also helps the reticle appear more stable on target, which supports more consistent shot placement when shooting from improvised rests or benches.

The tactical turrets add a more deliberate adjustment style than capped hunting knobs. With 40.00 MOA of elevation and windage travel, they suit shooters who prefer dialing corrections rather than relying only on holdover. The 25.4 mm tube, 326.00 mm length, and 525.00 g weight keep the scope relatively slim and easy to balance on lighter rifles. Fully multicoated lenses, nitrogen filling, and waterproof, fogproof, shockproof construction round out a design that is meant to stay usable in damp weather, temperature changes, and regular transport to the range or field.

About Discovery Optics

Discovery Optics, presented by the company as DISCOVERYOPT, states that it was established in 2009 and lists its main operations in Bao'an, Shenzhen, Guangdong, China. The company focuses on shooting and hunting optics, with a product range that includes rifle scopes, thermal imaging products, and other electro-optical sighting devices. Its riflescope lineup spans series such as XED, ED, LHD, and HD, showing a catalogue that covers both conventional optical sights and more advanced observation and aiming equipment.

Within the riflescope category, Discovery Optics offers models with both first-focal-plane and second-focal-plane reticles, reflecting a broad approach that serves hunters, recreational shooters, and users looking for tactical-style optics. The brand also lists thermal imaging solutions for hunting, which places it across both traditional glass optics and digital electro-optics rather than in only one segment of the market.
