Reciprocating gun stock with shrouded lock switch

A reciprocating stock and interface system for a semi-automatic firearm, said stock comprising:

• a bearing element adapted for attachment to a semi-automatic firearm to establish a constrained path of reciprocation,
• a handle adapted to be grasped by a user's hand, said handle including an opposing surface for directly interacting with said bearing element of the firearm so that in use said handle freely reciprocates back-and-forth relative to the firearm trigger along a constrained path, said handle including a finger rest, said finger rest configured to stabilize a user's trigger finger in a partially extended condition so that in use the user's trigger finger stretches in front of the trigger while the remaining fingers of the user's hand grasp said handle, said finger rest and said handle being fixed together as a unit,
• a lock carried on and moveable with said handle, said lock operatively interactive between said handle and said bearing element, said lock having a manually actuated switch movable between locked and unlocked positions so that in said locked position said handle is fixed relative to the firearm 1 trigger and in said unlocked position said handle is free to reciprocate relative to the firearm trigger,
• a shroud at least partially covering said switch to prevent said switch from being unintentionally repositioned, and
• wherein said at least one opposing surface comprises a channel formed in said handle and having an open front and a closed back, said channel configured to matingly receive said bearing element, said lock including a retractable pin, said bearing including at least one detent, said retractable pin selectively insertable into said detent to arrest movement of said handle relative to said bearing element, said bearing including a track, said track terminating at a rear stop, a tip of said retractable pin being disposed within said track and engageable with said rear stop to limit overtravel of said handle.

• a shroud at least partially covering said switch to prevent said switch from being unintentionally repositioned, and
• wherein said switch has a width in said locked position that is not greater than the width of said web portion, wherein said switch has a length that is greater than the width of said web portion so that in said unlocked position said switch protrudes beyond the sides of said web portion.
