The GPO Spectra 6x 3-18x56i is a riflescope by GPO German Precision Optics with a 6x zoom (3-18x), a 56 mm objective, a 30 mm main tube and an illuminated BRi reticle in the second focal plane (SFP). The 56 mm objective and magnification up to 18x make it ideal in the most difficult light conditions and at long range, with parallax adjustment from 10 m to infinity.
The illuminated BRi glass ballistic reticle offers additional aiming points below the centre for longer-range shots. This is the new generation Spectra 6x: HD lens system for transmission, resolution, colour rendition and edge-to-edge sharpness, precise mechanics with tool-free zeroing and a removable throw lever. The iControl illumination, made in Germany, switches off after three hours, warns at 15% battery and, thanks to new angle sensors, turns the reticle off when the rifle is tilted, reactivating it in a fraction of a second when it returns to the shooting position (function can be disabled).
