Decent pistol sight - Viridian OPMOD Omega Closed Emitter Green Dot Sight, ACRO Mounting w/RMR adapter And High Picatinny Mount

Most of the features of an Aimpoint for half the price. Solid construction, and the ACRO mount is very secure. The optic itself is bright and clear, but the dot projection is more affected by my visual astigmatism than any dot I've used before. The dot appears somewhat distorted in the sight window compared to others, but it's not much of a distraction and the aimpoint is accurate.
