DiscoveryOpt MS 6-24x42AOAC – Reliable Entry-Level Riflescope with Front Parallax
The DiscoveryOpt MS series was designed from the ground up to offer shockproof, dependable, and affordable riflescopes for those who don't want to compromise on core performance. The MS 6-24x42AOAC is one of the most popular members of the series, and can be seen as the direct successor to the beloved VT-R 6-24x42AOAC — inheriting many of its strengths while improving the reticle and overall build quality.
Magnification Range and Optics
The 6–24x magnification range allows highly flexible use. At lower magnification it handles medium distances of around 100 metres comfortably, while at 24x it delivers sufficient resolution for serious precision shooting. The 42 mm objective lens provides good light-gathering capability — the 6.8 mm exit pupil at low magnification produces a bright, pleasant image even in twilight conditions.
The lens system is fully multi-coated, improving light transmission and reducing reflections for a more contrasted and sharper image.
Reticle – Fine Wire HK Design
One of the key features of the MS 6-24x42AOAC is its fine wire HK reticle, positioned in the second focal plane (SFP). This means the reticle size remains constant regardless of magnification — an advantage for shooters who work at a fixed magnification and prefer a consistent aiming point.
The reticle features both red and green illumination, making it significantly easier to aim in low-light conditions or against dark backgrounds. Illumination intensity is adjustable.
Front Parallax Adjustment (AO)
The parallax adjustment (Adjustable Objective) on the objective bell ring is adjustable from 10 yards to infinity. This is particularly important for airgun shooting, where parallax error at short distances can be disruptive. Accurate focusing also results in a sharper image.
Adjustment System – 1/4 MOA Clicks
Both elevation and windage adjustments operate with a 1/4 MOA click value, with a total travel of 60 MOA in each direction. This provides sufficient adjustment range for most distances and ammunition types. The turrets offer a positive, tactile click feel.
Construction and Dimensions
- Tube diameter — 1 inch (25.4 mm), compatible with standard rings
- Length — 362 mm, compact and well-balanced
- Weight — 553 g, manageable without feeling flimsy
- Shockproof construction — tested for airgun recoil and centrefire firearms
- Fog-proof and water-resistant — nitrogen-filled to prevent internal fogging
Compatibility
The 1-inch tube is the most common size, making it compatible with virtually any standard rings or rail-mounted bases. It performs well on airguns, small and medium calibre hunting rifles, and target shooting setups alike.
Who Is This Scope For?
The MS 6-24x42AOAC is primarily aimed at those who are new to precision shooting, or who need a reliable, easy-to-use riflescope for airgun sport shooting. It is also a solid choice for those looking for a dependable secondary optic for field and range use. In terms of price-to-performance ratio, it is currently hard to find a comparable alternative at this level on the market.
User Feedback from Around the World
Feedback on the Discovery Optics MS series is generally positive. A recurring theme is that the series "offers excellent glass quality for the price and holds zero reliably." Many users highlight that the illuminated reticle is unobtrusive but genuinely helpful against dark backgrounds. The scope is especially popular among airgun shooters due to its short parallax adjustment range, and is widely used at 50–100 metre distances on PCP airguns. Some users noted that the eye box becomes somewhat tight at 24x, and the field of view naturally narrows at higher magnifications — though this is typical for this price and size category. Overall, user feedback consistently describes this as an honest, dependable scope that regularly exceeds expectations.
