Abstract: A shaft balancing device for insertion into a shaft including a generally flat cylindrical band having an outer surface, an inner surface and a set of two crush points thereon. A balancing weight is attached to the outer surface of the band between the set of crush points. The device is inserted into the shaft and the crush points are plastically deformed radially outward creating spring force which holds the balancing weight to the inner surface of the shaft. The band has a curved connecting portion between the two crush points having a radius of curvature slightly greater than the curvature of the shaft. The balancing weight has a radius of curvature slightly greater than the radius of curvature of the curved connecting portion and slightly less than the radius of curvature of the shaft.

Abstract: The present system provides a detachable cup or receptacle for receiving the butt stock of a weapon so that a greater portion of the surface area of the butt stock is stabilized when aiming and firing a weapon. The system provides fastening means for removably fastening the cup to the uniform of a shooter when wearing body armor. For ease of use, the system includes a graduated positioning system that can receive the butt stock and allow it to slide into place where, in one embodiment, it slips into a recessed area that matches the dimension of the butt stock for greater security of the positioning of the weapon. The weapon can be easily removed from the cup so that the shooter's mobility and the ability of the shooter to move the weapon back and forth from a shooting position is not compromised.
