DiscoveryOpt ED-PRS Gen2 5–25×56 SFIR FFP-Z Riflescope – Precision Optics Without Compromise

The DiscoveryOpt ED-PRS Gen2 5–25×56 is a professional-grade first-image-plane (FFP) riflescope designed specifically for long-range precision shooting. This 2023 second-generation model, equipped with Extra-low Dispersion (ED) glass, offers outstanding optical clarity and sharpness even at a high magnification of 25×. The 34 mm, one-piece machined aerospace aluminum tube gives the scope a solid, reliable construction and allows for a larger internal adjustment range than the competition. It is an ideal choice for long-range sport shooting (PRS competitions, precision target shooting) and hunters who strive for a sure hit even at extreme distances. All this is provided in a user-friendly, durable form that resists recoil and is completely waterproof and dustproof, so it can withstand the harshest conditions.

Main features

• 5-25x magnification, 56mm lens – Wide zoom range from mid-range to ultra-long-range shots. The large 56mm front lens collects plenty of light, delivering bright and clear images even in low light.

• Japanese ED glass and multi-layered lens coatings – Premium extra-low dispersion glass minimizes chromatic aberration and distortion, resulting in crystal-clear, sharp images throughout the entire magnification range. Multi-layered coatings on the entire lens surface ensure outstanding light transmission and contrast.

• First-Plane, MOA-Based Illuminated Reticle – The riflescope’s engraved reticle is located in the first image plane, so the size of the ballistic markings changes with magnification. This ensures that holdover and range-estimating markings are applied equally at all magnifications, making it easier for the shooter to make long-range shots. The red-illuminated center reticle is a great help in low light – it is clearly visible against the dark background of the target without excessively blinding the shooter.

• Zero-Stop Precision Turrets with 1/4 MOA Clicks – The heavy-duty tactical turrets have a firm click (1 click = 0.25 MOA) for precise alignment. The zero point (Zero-Stop) can be set and locked, making re-shooting/zeroing the scope a breeze, and the zero point can be reset quickly and securely at any time without over-tightening. The turrets are lockable, preventing accidental adjustment in the field.

• Huge internal adjustment range – Thanks to the 34 mm tube and advanced internal mechanics, approximately 122 MOA vertical and 60 MOA horizontal adjustment range are available. This is an outstanding value in this category and allows you to shoot at extreme distances without external ballistic aids (e.g. raised rail).

• Side Parallax from 25 yards (22.86 m) to infinity – The side parallax adjustment dial provides a sharp image from an extremely close distance of 25 yards (~23 m). Whether it's close range, airgun use or shooting beyond 1000 m, parallax error can be easily eliminated across the entire range.

• Durable, Weatherproof Design – The riflescope’s one-piece, aircraft-grade aluminum barrel and superior seals guarantee 100% water and moisture resistance. Thanks to its nitrogen gas filling, its internal lenses do not fog up, even in the event of sudden temperature changes. Its shock-resistant construction (tested to 1500 G) can withstand the recoil of even the most powerful large-caliber weapons and spring-loaded air rifles, making it a reliable long-term shooting companion.

Advantages over competitors

The DiscoveryOpt ED-PRS Gen2 5–25×56 offers premium features that other manufacturers often charge a lot more for. Compared to the popular Vortex Venom 5–25×56 FFP or Arken SH4 Gen II models, the Discovery offers a larger adjustment range (122 MOA vs. ~90 MOA) and an exceptionally clear image thanks to Japanese ED glass. The Zero-Stop function – which is easy to adjust and reliable on the Discovery – is not available at all on many competitors in this price range or is not as user-friendly (some Arken models are considered more complicated to set the zero point). We also get some of the know-how of the Delta Stryker and Element Theos high-end riflescopes in this model: the first image plane, illuminated MIL reticle and the outstanding image quality of ED glass. While a Delta Stryker or Element Theos costs several times more than the Discovery ED-PRS Gen2, the Discovery's optics are unbeatable in terms of price-performance ratio - users say its performance is close to that of much more expensive premium models, making it an excellent alternative for both hobby and competitive shooters.

Recommended use and target audience

This riflescope is primarily designed for long-range precision shooting: it is an ideal choice for competitors in PRS (Precision Rifle Series) and other long-range shooting competitions. Thanks to its high magnification and precise ballistic reticle, shots over 1000 meters are no problem. It is also recommended for hunters and sport shooters who want to increase their accuracy at extreme distances - for example, during long-range hunting (mountain hunting, long-range game damage control) or long-range hobby shooting. Due to the parallax adjustable from 25 yards, the scope can be used in many ways: either mounted on a high-performance air rifle for target shooting within 25 m, or on a large-caliber rifle for shooting distances of several kilometers. Due to its solid construction and reliable mechanics, it is also recommended for those who are looking for durable optics with intensive use or strong recoil. In short, the Discovery ED-PRS Gen2 is excellent for anyone who expects uncompromising accuracy and reliability from their telescope.

Summary of user reviews

The opinions of customers who have tried the product are extremely positive. Several point out that the sharpness and clarity of the image are surprisingly good even at maximum magnification of 25×, competing with significantly more expensive optics. The precision and repeatability of the turret adjustments are praised: the clicks are loud and clear, the tracking is accurate, so the shot can be made quickly and the hit point can be held stably. Users really like the simplicity and reliability of the Zero-Stop system – according to some feedback, it is easier to use than the zero point adjustment mechanism of some competitors (e.g. Arken). The excellent price-performance ratio also received a lot of praise: according to customers, they get an unusually rich set of features and quality for this much money. The premium accessories included in the package (such as 34 mm thick-walled mounting rings, several hood extensions, a leveling tool, and a lens cleaning kit) add additional value to the product, as other brands would require you to pay extra for these. The only compromise some users cite is the significant weight and size of the telescope – it weighs almost 1.25 kg and has large towers – but most users add that this robust construction is a necessary price for excellent optical performance and durability, which is worth paying. Overall, the Discovery ED-PRS Gen2 5–25×56 riflescope has lived up to its expectations based on user feedback: it is reliable, accurate, and brings the qualities of much more expensive telescopes at an affordable price.
