Abstract:
1. A coupling pin for coupling weapon components, comprising: an elongated body comprising an outer surface, a longitudinal bore, and a second bore, the second bore extending between the outer surface and the longitudinal bore, the outer surface of the body comprising: a longitudinal recess opposite an opening of the second bore; a first supporting area adjacent one end of the body; a second supporting area adjacent another end of the body; and a positioning area between the first and second supporting areas, the longitudinal recess being at least partially formed within the positioning area, wherein the coupling pin is insertable into aligned first apertures of a first weapon component, the first apertures defined by supporting surfaces, the supporting surfaces to be axially positioned relative to the first and second supporting areas when the coupling pin is inserted into the weapon components, wherein the coupling pin is insertable into a second aperture of a second weapon component, the second aperture defined by a positioning surface, the first apertures being substantially aligned with the second aperture, the positioning surface to be axially positioned relative to the positioning area when the coupling pin is inserted into the weapon components; a spring loaded tension pin positioned in the longitudinal bore; and a tension element positioned in the second bore, wherein the tension pin is spring biased towards and engages the tension element to urge the tension element out of the second bore toward and into engagement with the positioning surface to at least one of adjust or brace the positioning surface relative to the supporting surfaces at substantially a right angle relative to a longitudinal axis of the coupling pin and to urge a surface defining the second aperture into or toward the longitudinal recess.
