Detachable hologram assembly (10) for a compact holographic sight includes a hologram of a reticle image mounted within a resilient, detachable frame (16). The frame includes a pair of generally planar, non-parallel registration surfaces and an aperture extending through the frame at the junction of the registration surfaces. A hologram mount (18), also including a pair of registration surfaces which are complimentary to those of the frame is affixed to, or integral with, the sight. A fastener secures the hologram assembly to the mount. The angle of one registration surface relative to the other registration surface of the hologram frame is preferably slightly less than the angle between the registration surfaces of the hologram mount, so that as the frame is secured by the fastener to the mount, the ends of the registration surfaces of the frame are deflected, urging the registration surfaces into secure, registered contact with the mount. |
