Claim:
A reciprocating stock for a semi-automatic firearm, said stock comprising: a handle adapted to be grasped by a user's hand, said handle including an opposing surface for directly interacting with a 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 the firearm, 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 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 handle includes a butt end adapted to be placed against the shoulder of a user, said handle further including a web portion extending forwardly from said butt end, and an undersurface having a generally continuous extension along the bottom of said web portion, said shroud having a width not greater than the width of said web portion, wherein said switch has a width in said locked position that is not greater than the width of said web portion, and 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.
