Slide stock for firearm with retractable lock pin

摘要

A bump stock and interface system for a semi-automatic firearm. In use, the user grasps a handle with one hand and places an index finger of the same hand firmly on a finger rest. When intending to fire a round of ammunition, the user pushes the firearm receiver forward with another hand so that the trigger collides with the immobilized finger on the finger rest. Recoil force separates the trigger from the user's finger on the finger rest. The user again pushes forward the receiver to repeat the firing cycle. A lock is selectively activated to arrest longitudinal movement of the firearm relative to the handle, thereby returning the firearm to normal semi-automatic functionality. The lock includes a retractable pin having a tip that rides in a track having a rear stop to limit over-travel of the handle.

主权项

1. A sliding bump stock for a semi-automatic firearm, said stock comprising:
a handle adapted to be grasped by a user's hand, said handle including a finger rest, said finger rest extending forwardly from said handle and configured to stabilize the end of 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 moveable together as a unit, said handle including an opposing surface for directly interacting with a bearing element of the firearm so that said finger rest and said handle are able to reciprocate in concert relative to the firearm trigger back-and-forth along a constrained linear path, and a lock movable toward and away from a locked position for selectively stopping reciprocating movement of said finger rest relative to the firearm trigger.
