MM4 77 Fieldscopes are the latest evolution of the MM concept pioneered and developed by Opticron over the past 25 years to meet the ever-growing demand for lightweight, space saving high performance field equipment.
Designed & manufactured in Japan, the 77mm HDF ED optical system delivers a new benchmark for resolution and colour contrast and comfortably outperforms older Opticron 80mm models. What is more remarkable is the size and weight of the overall package. The MM4 77 GA ED/45 is just 320mm/12.6” long and weighs 1259g/44.4oz fully armoured. These figures read like a 65mm which cannot deliver the light transmission or apparent resolution of this 80mm class device.
