Abstract: A proven military combat-type weapon with the stock removed therefrom converted to an improved tactical weapon by addition of retrofit assemblies which include a collapsible and bilaterally pivoting stock, a front stabilization system, and a sighting system. This improved tactical weapon has the characteristics of reduced exposure to enemy fire by allowing the operator to fire while under cover, and increased weapon stability by the utilization of the front stabilizer assembly. Utilizing this invention, the operator is able to shoulder support and fire the weapon with minimal exposure to enemy fire. Furthermore, by exerting force to (leaning against) the weapon stock, the weapon is pinned between the operator and the object (i.e., wall, tree, etc.). The amount of gun movement is reduced and the stability of the weapon is increased over a weapon which is only hand held when the gun is fired.
