GPO SPECTRA 5x 3-15x56i G4i FIBER ILLUMINATED RIFLESCOPE

The GPO Spectra 5x 3-15x56i is designed for hunters who need a versatile riflescope that performs across different hunting situations. Its 3–15x magnification range allows the shooter to adapt to varying distances, while the 56 mm objective lens gathers more light to provide a clear image in challenging lighting conditions. This makes it particularly suitable for early morning and evening hunting.

The HD optical system delivers 90% light transmission, high resolution, natural colour reproduction and edge-to-edge image sharpness. The G4i fibre reticle produces a clearly defined, fine illuminated aiming point with high brightness. Fibre technology helps maintain a precise and clearly visible aiming point across a range of lighting conditions.

The riflescope features a 30 mm main tube, precise and robust mechanics, and tool-free zeroing turrets. A removable throw lever is included for quick and convenient magnification adjustment. Both elevation and windage offer an adjustment range of 250 cm at 100 metres, with a click value of 1 cm at 100 metres.

The iControl™ system manages reticle illumination automatically. The illumination switches off after three hours, and a low-battery warning is activated when approximately 15% battery capacity remains. Integrated position sensors also detect the riflescope's angle and switch off the illumination after a few minutes or immediately, depending on its position. When the riflescope returns to its normal position, the reticle illumination automatically switches back on. This function can be activated or deactivated by the user.

Parallax adjustment from 10 metres to infinity allows the riflescope to be adapted to different shooting distances. With its versatile magnification range and compact design, the Spectra 5x 3-15x56i is suitable for a wide range of hunting applications.

FAQ

What is the GPO Spectra 5x 3-15x56i suitable for?
It is suitable for a wide range of hunting situations, particularly in low-light conditions. The 3–15x magnification range allows it to be used at both shorter and longer distances.

Is this riflescope suitable for low-light hunting?
Yes. The large 56 mm objective lens and HD optical system with 90% light transmission help gather available light and provide a clear, sharp image.

What reticle does the GPO Spectra 5x 3-15x56i use?
It features a G4i fibre illuminated reticle that produces a fine, clearly defined illuminated aiming point.

How does the iControl™ illumination system work?
The illumination switches off automatically after three hours. Position sensors also detect the riflescope's angle and switch off the illumination depending on its position. When the riflescope returns to its normal position, the illumination automatically switches back on.

Does the riflescope have parallax adjustment?
Yes. Parallax can be adjusted from 10 metres to infinity.

What is the adjustment range of the GPO Spectra 5x 3-15x56i?
Both elevation and windage have an adjustment range of 250 cm at 100 metres. Each click moves the point of impact by 1 cm at 100 metres.

What mounting rings are required?
The riflescope has a 30 mm main tube, so 30 mm mounting rings are required.
