The Bushnell AR Optics TRS-25 HiRise is a finely executed red dot scope featuring a 3-MOA red dot for precision shot placement. 11 brightness settings provide optimum illumination in any light condition. The supplied riser block positions the Bushnell T.R.S. 25 Red Dot Scope at optimum height on flat top ARs and tactical shotguns. This sight by Bushnell was leading the charge for 2013. The Bushnell 1x M.P. Red Dot Scope conserves battery life by self regulating brightness based on available light and power down when the protective storage hood is attached.
