Abstract
Abstract The rear sight of a firearm has a peephole device formed by a hollow tube, each of the two ends of which are closed by a peephole. Each peephole has a central orifice therein. The orifice of the peephole of the rear side has a larger diameter than the orifice of the peephole on the front sight side. Each peephole is pivotally mounted and cooperates with an elastic member which holds the peephole in its tube-opening or tube-closing position. In a further embodiment, two peepholes are provided at each end of the tube.
