GPO SPECTRA 5x 3-15x56

• 3-15x magnification range: Covers the practical span from woodland and field hunting to more deliberate shots at distance, so one riflescope can handle stand hunting, stalking, and open-ground use without feeling specialized to only one task.
• 56 mm objective lens: The large front lens and 90 % light transmission help maintain a brighter sight picture in poor light, which is especially useful when game appears at dawn, dusk, or under heavy cover.
• Second focal plane illuminated reticle: The reticle stays visually fine as magnification changes, keeping the target less obscured at higher power, while the red illumination improves aiming-point visibility against dark backgrounds.
• Side parallax adjustment from 9 m - inf: Fine-tuning parallax over a very wide distance range helps keep the image and reticle on the same focal plane, which supports more precise shot placement from close-range practice to longer hunting shots.
• Capped multi-turn turrets: The capped design protects settings from accidental movement in the field, while the generous 25.00 mrad elevation and windage range gives the scope enough adjustment latitude for a broad range of common hunting calibers.

About the GPO SPECTRA 5x Series

The GPO SPECTRA 5x series sits in the brand’s hunting riflescope range as a versatile line built around a 5x zoom ratio, practical field handling, and solid low-light performance. These scopes are designed for hunters who want one optic to cover several styles of use rather than a narrowly specialized setup. Across the series, the emphasis is on a useful balance of magnification range, compact proportions, and dependable mechanics that suit stalking, stand hunting, and general-purpose hunting optics.

A defining trait of the line is its combination of HD lens system design, GPObright lens coatings, and a hunting-oriented feature set that focuses on image brightness, contrast, and edge-to-edge sharpness. SPECTRA 5x riflescopes commonly pair a 30 mm main tube with second focal plane reticles intended for straightforward aiming in real hunting conditions. Depending on the model, the series also incorporates illuminated reticles, side parallax adjustment, and practical turret systems that favor reliability and ease of use over unnecessary complexity. The result is a family of riflescopes aimed at hunters who need clear optics, sensible controls, and enough flexibility to move confidently between shorter and longer shooting distances.

About the GPO SPECTRA 5x 3-15x56

The GPO SPECTRA 5x 3-15x56 is the low-light oriented model in the series, combining a broad 3-15x magnification range with a large 56 mm objective lens. That combination makes it especially well suited to stand hunting, evening field use, and any situation where the light is fading but precise shot placement still matters. At 3x, the scope remains manageable for shorter and medium distances; at 15x, it gives the shooter enough image scale for more deliberate aiming across open ground.

Its optical layout is built around a 90 % light transmission figure, fully multicoated lenses, and a generous 95.00 mm eye relief. In practice, this supports a bright, comfortable sight picture and stable head position, which is valuable on heavier-recoiling hunting rifles and during longer observation before the shot. The field of view of 11.10 m/100m to 2.30 m/100m reflects the scope’s dual role: enough width at low power for situational awareness, and enough magnification at the top end for precise target evaluation.

The scope uses a second focal plane illuminated reticle with red illumination, a layout that keeps the reticle appearance consistent as magnification changes. For hunting, that means the aiming point stays easy to read without becoming overly heavy at higher power. The side-focus parallax adjustment from 9 m - inf adds precision across a wide range of distances, while the capped multi-turn turrets protect settings during transport and field carry. A 30 mm tube, nitrogen filling, and waterproof, fogproof, and shockproof construction complete a riflescope designed for regular hunting use in changing weather and light.

About GPO

German Precision Optics (GPO) was founded in 2015 by former optics-industry executives and specialists. The company designs and engineers its products in Germany and is headquartered in Inning am Ammersee, near Munich, Germany. GPO focuses on sporting optics for hunting, nature observation, and sport shooting, with a product portfolio that includes riflescopes, red-dot sights, binoculars, spotting scopes, and laser rangefinders.

Within its riflescope offering, PASSION and SPECTRA are the core product lines. This reflects GPO’s emphasis on practical field optics that combine modern optical design with category-specific features for hunters and shooters. The brand’s broader range also includes products such as RANGEGUIDE binoculars, which integrate optical viewing with laser rangefinding and angle calculation, showing the company’s focus on combining optical performance with useful field functionality.
