Slider mechanism for collapsible firearm stock

A stock assembly comprising:

• a stock body defining an internal cavity between a proximal end and a distal end of the stock body;
• and
• a slider assembly comprising:
• a first panel having an interior surface and an exterior surface, the interior surface of the first panel partially defining the internal cavity and defining a first channel;
• a second panel having an interior surface and an exterior surface, the interior surface of the second panel partially defining the internal cavity and defining a second channel;
• a fastener extending through the internal cavity and coupling the first panel and the second panel together, wherein the first panel and the second panel are each configured to move together along a track defined by the stock body;
• a lock pin disposed in the internal cavity;
• and
• a release pin extending through the lock pin and having a first end portion extending into the first channel and a second end portion extending into the second channel;
• wherein:
• the release pin is configured to travel along a fixed path defined by the first channel and the second channel in response to a movement of the first panel and the second panel along the track;
• and
• the release pin is configured to cause the lock pin to transition from a first position to a second position in response to the movement;
• and
• a lever configured to transition between a locked position and an unlocked position, wherein with the lever in the locked position, the lever is configured to inhibit the movement of the first panel and lock a portion of the lock pin in a pocket defined by a receiver extension.

A buttstock comprising:

• a slider panel defining a channel;
• a biasing mechanism disposed in an internal cavity defined by the buttstock, the biasing mechanism configured to bias the slider panel toward a distal end of the buttstock;
• a lock pin disposed in the internal cavity;
• a release pin affixed within the lock pin and having an end portion extending into the channel, wherein the release pin is configured to translate longitudinal motion of the slider panel to perpendicular motion of the lock pin;
• and
• a lever configured to transition between a first state and a second state;
• wherein:
• with the lever in the first state, the lever is arranged to inhibit retraction of the slider panel toward a proximal end of the buttstock and lock a portion of the lock pin in a pocket defined by a receiver extension;
• and
• with the lever in the second state, the lever is arranged to permit retraction of the slider panel toward the proximal end of the buttstock.
