Abstract: An improved aiming tube pivot assembly for use in a sighting and/or aiming apparatus which comprises an aiming tube axially mounted within an outer tube (or housing). A support ring supports the aiming tube within the outer tube in a gimbal-like arrangement by means of ball bearings and set screws. The ball bearings are secured intermediate the aiming tube and the support ring via apertures in the outer tube. The set screws are threadedly mounted in the support ring and engage the outer surface of the outer tube. A movable cover tube can be mounted on the outer tube and substantially encloses the end of the outer tube and the support ring.
