Folding stock for firearms and firearms employing same

摘要

A folding stock includes a butt plate that assumes its operational orientation in both the extended and the folded positions of the stock. A pivot arm is pivotably mounted on a mount that is adjustably inserted into recesses in the rear of the receiver of the weapon. The pivot arm pivots about the mount pivot axis at its one end and has a butt member pivotably mounted at its other end. The butt member has a horizontal stock portion and a vertical butt-plate portion at the rear. A spring fastened to the mount acts as a lock for both the pivot arm and the butt member.
