Abstract: A sight is provided for a weapon or other device requiring manual alignment with a target along a viewing line, the weapon having a barrel with front and rear sights. The sights are structured to provide sufficient visual cues to the shooter to enable effective aiming while focusing on the target rather than the sight. The rear sight closer to the shooter has a standing planar member perpendicular to the gun barrel. The rear sight has a rounded outer periphery and a substantially circular central opening joined to the top edge of the rear sight along a discontinuous edge forming rounded wings, and corresponding to a tangent of the circular opening. The front sight has a solid cylinder whose axis is parallel to the axis of the gun barrel. The front sight cylinder is dimensioned relative to the rear sight opening to substantially fill the rear sight opening when the shooter's view is aligned along the barrel to the target.
