View Patent ↗An automatic or semiautomatic blackrifle type rifle having a receiver and a bolt carrier movably coupled to the receiver. An action system is connected to the bolt carrier for cycling the bolt carrier in the receiver. A folding butt stock is connected to the receiver, the folding butt stock being both foldable and collapsible.
1. An automatic or semiautomatic rifle, comprising:
a receiver;
a receiver extension, secured to the receiver;
an action spring received within the receiver extension, the action spring cooperating with a bolt carrier for cycling the bolt carrier in the rifle, and
a folding butt stock portion pivotally connected to the rifle at a distal end of the receiver extension with respect to the receiver, wherein the folding butt stock portion is capable of movement from a first position extending rearwardly from the distal end of the receiver extension to a second position wherein the folding butt stock portion extends forwardly from the distal end of the receiver extension, wherein the folding butt stock portion comprises a butt stock slidably mounted to an extension for movement between an extended position wherein the folding butt stock has a first length and an unextended position wherein the folding butt stock has a second length the second length being less than the first length, wherein the extension is pivotally secured the rifle by a coupling.
2. An automatic or semiautomatic rifle, comprising:
a receiver;
a receiver extension, secured to the receiver;
an action spring received within the receiver extension, the action spring cooperating with a bolt carrier for cycling the bolt carrier in the rifle, and
a folding butt stock portion pivotally connected to the rifle at a distal end of the receiver extension with respect to the receiver, wherein the folding butt stock portion is capable of movement from a first position extending rearwardly from the distal end of the receiver extension to a second position wherein the folding butt stock portion extends forwardly from the distal end of the receiver extension, wherein the folding butt stock portion has an axis that is aligned with an axis of the receiver extension when the folding butt stock portion is in the first position, and wherein the axis of the folding butt stock portion is parallel with the axis of the receiver extension.
3. The rifle of claim 1 , wherein the folding butt stock portion further comprises a butt portion pivotally mounted to the folding butt stock for movement between a first position wherein the butt portion is parallel to the axis of the folding butt stock portion and a second position wherein the butt portion is orthogonal to the axis of the folding butt stock portion.
4. An automatic or semiautomatic rifle, comprising:
a receiver;
a receiver extension, secured to the receiver;
an action spring received within the receiver extension, the action spring cooperating with a bolt carrier, and
a folding stock connected to the receiver, the folding stock having a first butt stock portion and a second butt stock portion,
wherein the first butt stock portion folds about a first axis at a distal end of the receiver extension with respect to the receiver, and wherein the second butt stock portion folds about a second axis proximate to a distal end of the first butt stock portion.
5. The rifle of claim 4 , wherein the first butt stock portion is capable of movement between a first position, wherein an axis of the first butt stock portion aligns with an axis of the receiver extension and extends away from the distal end of the receiver extension in a rearward direction and a second position, wherein the axis of the first butt stock portion is no longer aligned with the axis of the receiver extension and wherein the second butt stock portion is slidably mounted to the first butt stock portion for movement between an extended and unextended position with respect to the first butt stock portion such that the folding stock is capable of having a variable length.
6. A folding butt stock for a rifle, comprising:
a folding butt stock portion pivotally connected to the rifle at a distal end of a receiver extension with respect to a receiver of the rifle, wherein the folding butt stock portion is capable of movement from a first position extending rearwardly from the distal end of the receiver extension to a second position wherein the folding butt stock portion extends forwardly from the distal end of the receiver extension, wherein the folding butt stock portion comprises a butt stock slidably mounted to an extension for movement between an extended position wherein the folding butt stock has a first length and an unextended position wherein the folding butt stock has a second length the second length being less than the first length, wherein the extension is pivotally secured the rifle by a coupling, wherein the folding butt stock portion further comprises a butt portion pivotally mounted to the folding butt stock for movement between a first position wherein the butt portion is parallel to the axis of the folding butt stock portion and a second position wherein the butt portion is orthogonal to the axis of the folding butt stock portion.
