The UTG 4.0 MOA Red Dot Sight (brand part no. SCPDS3039W) is a 30mm-tube reflex sight built by Leapers with an integral Quick Detachable mount that goes straight onto any Picatinny rail. It projects a crisp 4.0 MOA dot in either red or green, using UTG’s emerald anti-reflection coatings to keep the sight picture clear in bright light, and its optimal height design lets it co-witness with standard iron sights. Whether it is going on a home defense carbine, a shotgun, or a pistol-caliber carbine, the UTG 4 MOA red dot delivers a fast, repeatable aiming point for close to mid-range shooting.
