Collapsible firearm butt-stock assembly

A collapsible firearm butt-stock assembly comprising:

• a buffer tube housing having a hole to receive a buffer tube;
• a first guide rod and a second guide rod;
• a shoulder stock coupled to said guide rods;
• and
• a locking mechanism for locking said shoulder stock in at least one fixed position relative to said buffer tube housing;
• wherein said buffer tube housing is provided with respective guide holes that are configured so that said guide rods can slide in said guide holes to permit movement of said shoulder stock relative to said buffer tube housing such that the shoulder stock can be moved towards and away from said buffer tube housing in a lengthways direction of said buffer tube housing,
• wherein said guide rods each have a plurality of guide rod recesses disposed at spaced apart locations along said guide rods to define respective extended positions of said shoulder stock,
• wherein said locking mechanism comprises a first locking member that is releasably engageable with the guide rod recesses of said first guide rod, a second locking member that is releasably engageable with the guide rod recesses of said second guide rod and a user operated actuator operable to release said first and second locking members from engagement with said guide rod recesses, and
• wherein said actuator is configured to be movable by a said user in a direction parallel to the lengthways direction of said first and second guide rods to release said first and second locking members from engagement with said recesses.

A firearm comprising a collapsible firearm butt-stock assembly, wherein said collapsible firearm butt-stock assembly comprises:

• a housing provided with a first guide hole and a second guide hole;
• a shoulder stock coupled to a first guide rod that is inserted in said first guide hole and a second guide rod that is inserted in said second guide hole, the guides rods being configured so as to be able to slide in the respective guide holes to allow movement of said shoulder stock relative to said housing;
• and
• a locking mechanism comprising at least one locking member releasably engageable with at least one guide rod recess defined by said guide rods to limit said movement of the shoulder stock relative to said housing, and a user operable actuator that is movable in i) a first direction that is away from said shoulder stock to release said at least one locking member from engagement with said at least one guide rod recess to allow said guide rods to slide in said guide holes so that said shoulder stock can move relative to said housing and ii) a second direction that is towards said shoulder stock to cause said at least one locking member to engage said at least one guide rod recess.
