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 version belongs to the previous generation of the Spectra 6x series: high-transmission GPObright coating, Double HD objective, tool-free zeroing turrets with 1 cm clicks and an included throw lever. The iControl illumination is adjustable in intensity, switches off automatically after three hours and warns when the battery reaches 15%.
