AGM SPECTRUM LRF 4K 50MM 3.5-28X THERMAL RIFLE SCOPE The NEW Spectrum LRF 4K digital day & night vision scope from AGM utilizes many of the features that shooters have come to know and love in the Spectrum-IR, but with one big addition: a 1,000-meter integrated laser rangefinder (LRF). This feature helps alleviate a common issue many shooters experience when hunting with digital optics - the lack of depth perception that comes with using a digital screen. The Spectrum LRF 4K pairs that LRF functionality with an advanced high-resolution 3840A-2160 detector, which works in conjunction with a high-quality 1920A-1080 OLED display.
