The Meprolight MPO-S RMSc green bullseye pistol sight is a low-profile open emitter built for concealed carry handguns (brand part no. 901141181). Its sleek profile is designed to minimize snags for a faster draw, and the RMSc footprint allows direct mounting to compatible slimline pistols. This version carries a green 3/33 MOA bullseye reticle, which gives a precise center dot inside a larger ring for quick sight alignment. Meprolight pairs it with automatic and manual brightness control and a battery that Meprolight says gives two and a half years of illumination. It is a compact optic for a carry gun that needs to stay slim.
