A collapsible reflective optical sight for a firearm includes a base that mounts the optical sight to the firearm, a lens attached to and rotatable with respect to the base, wherein the lens includes a first optic with a reflective surface and the lens is folded with respect to the base for storage in a collapsed configuration and is angled with respect to the base in a deployed configuration for use in aiming the firearm, a light source on the base that reflects light off the reflective surface of the first optic to a user for aiming the firearm, and a mechanical sight on the base for aiming the firearm when the lens is in the collapsed configuration.

Implementations of a rear sight block for AK-type rifles are provided. In some implementations, the rear sight block may be drop-in-compatible with most AK-type rifles and performs several functions (e.g., providing a guide hole for the piston of an AK-type rifles operating system) associated with prior art rear sight blocks found on AK-type rifles. In some implementations, the rear sight block disclosed herein comprises an optic mounting interface having an integral rear sight notch therein, and at least one accessory mounting interface. In some implementations, the optic mounting interface places an optical gun sight secured thereto in line with the iron sights of the host AK-type rifle. In some implementations, the accessory mounting interface may be used to position a flashlight, laser, and/or other firearm accessory on the left (or right) side of the rear sight block.

A sight for a pistol has a sliding fit within a channel in the slide of the pistol. A fastener retains the sight to the slide. The fastener passes through a slot in the slide. The slot is surrounded by a countersink surface and has a major dimension oriented transversely to the longitudinal axis of the slide. The fastener has a conical head with a cone angle which may be the same as or different from the angle of the countersink surface.

The embodiments of the disclosed invention relate to fiber optic weapon sights that use a reflector to direct ambient light to a fiber optic rod and thus provide weapon sights that are bright in any lighting condition. In one instance, the reflector can have a concave shape, such as a spherical or parabolic shape, that can focus ambient light on the fiber optic rod and thereby significantly increase the brightness of the weapon sight. The embodiments of the present invention can accordingly provide enhanced fiber optic front and/or rear sights for weapons including rifles, pistols, and shotguns.
