I have a 16" AR with a 15" MWI rail and YHM quick deploy sights. Front sight sits on the end of the rail, rear sight sits behind a Bushnell TRS red dot on the rear of the receiver. The rifle will give consistent groups with quality ammo. However, My sights wont quite line up with POI. The rear sight is adjusted all the way left. Does anyone know what kind of issues will cause this?
