Portable reticle alingment device for firearms

A device for aiding in the cross-hair alignment of the reticle of a gun-mounted telescopic sight, said device comprising:

• a gun having a barrel, said barrel including a longitudinal barrel axis and at least one mounting boss, said mounting boss being already aligned with said longitudinal barrel axis;
• a telescopic sight having a rear viewing end, a front end which is closest to the muzzle of said barrel, and a reticle with at least one sighting hairline, said telescopic sight mounted to said at least one mounting boss of said gun;
• a bracket assembly attachable to said at least one mounting boss so that said bracket assembly, when attached to said at least one mounting boss, aligns with said longitudinal barrel axis;
• an optical assembly having a reference reticle positionable in the line of sight of said telescopic sight, said optical assembly being mechanically connected to said bracket assembly so that said optical assembly automatically aligns with said longitudinal barrel axis;
• and
• wherein said cross hairs of said reticle may be compared with and aligned with respect to said [superimposed]reference reticle of said optical assembly to align said cross hairs of said telescopic sight with respect to said bore axis of said barrel.

A device for aiding in the cross-hair alignment of the reticle of a gun having a gun barrel including a longitudinal barrel axis and a telescopic sight mounted on said gun, said telescopic sight having a viewing end and a reticle with at least one sighting hairline, said device comprising:

• a card having a viewing surface and a contact edge;
• at least one reference line located on said viewing surface and aligned with said contact edge, said contact edge being adapted to be positioned in abutting relationship with the mounting boss of said gun on which said telescopic sight is mounted independent of said telescopic sight so that said reference line automatically aligns with the axis of the barrel of said gun and so that said viewing surface lies adjacent to said reticle;
• and
• the relative position of said card abutted onto said mounting boss enables the orientation of said at least one sighting hairline Of said reticle to be compared with said reference line and adjusted to align the telescopic sight with the barrel axis of the gun.

A device for use in aligning the cross hairs of a telescopic sight mounted on a gun comprising

• a first reference card having parallel reference lines located on at least one surface;
• a second reference card having parallel reference lines located on at least one surface;
• a connecting bar joining said first and second cards to each other and holding said cards in a common plane;
• said connecting bar having at least one flat surface and being parallel to said reference lines of said reference cards, and
• each of said reference cards having a projection on one edge for securing one end of an resilient member, said resilient member securing said device to a portion of said gun adjacent to said telescopic sight.
