The GPO Spectra 8x 2–16x50i G4i Fiber expands GPO’s 8x zoom riflescope family by offering a compact version with a 50 mm objective lens.
The GPO Spectra 8x 2–16x50i G4i Fiber expands GPO’s 8x zoom riflescope family by offering a compact version with a 50 mm objective lens. It builds on the optical layout of the successful 1.6–13x44i and excels in image quality (color fidelity, transmission, resolution, edge sharpness), field of view, and mechanical stability.Its applications range from dynamic hunting to precise longer-range shooting at 16x. Parallax adjustment begins at 10 m. Technical data Magnification: 2x – 16x Field of View (FOV) @100 m: 20.5 m – 2.6 m Objective Diameter / Effective Diameter: 50 mm Exit Pupil (mm): 8.5 mm – 3.1 mm Eye Relief: 95 mm (3.74 in) Click Value / Travel per Click (@100 m): 1 cm per click Elevation Adjustment Range (total) @100 m: 320 cm Windage Adjustment Range (total) @100 m: 320 cm Parallax Compensation / Focus: 10 m – ∞ (side focus) Light Transmission: 90 % (ISO 14490-5:2005) Height without Covers: 61 mm (2.4 in) Width (fully extended): 83 mm (3.2 in) Length (overall): 345 mm (13.58 in) Tube Diameter (main tube): 30 mm Weight (without covers / accessories): 718 g Mechanical Outer Diameter (Objective end): 57.2 mm Mechanical Outer Diameter (Ocular end): 45.8 mm Reticle Type / Position: G4i Fiber, Second Focal Plane (SFP)
