The TRS-25 HiRise provides heavyweight performance. It features a 3 MOA red dot for precision shot placement, and 11 brightness settings to provide optimum illumination in any light condition. The supplied riser block positions the sight at optimum height on AR-15 flat tops or tactical shotguns and has a range of 70" @ 100 yds. It conserves battery life by self regulating brightness based on available light and power down when the protective storage hood is attached.
