Accessory for a firearm

Abstract

A magazine fed shotgun may not use the space within a magazine tube. An accessory, such as a light or a laser, may be inserted into the magazine tube. A switch that operates the accessory may be located on the pump grip of the shotgun. The switch may be connected to the accessory with a wiring harness that may extend through an opening in the tube. The opening may be elongated so that the wiring harness can move with the pump grip when the pump grip is cycled by an operator.

         9 . The accessory of  claim 1 , further comprising a capturing member configured to secure the body to the tube. 
     
     
         10 . A forend assembly comprising:
 a tube having a cavity and an opening in a side connecting to the cavity, the tube being configured to connect to a receiver of a firearm;   a forend having an outer surface, being configured to connect to a carrier and to slide along the tube;   a switch mounted on the outer surface of the forend;   a wiring harness positioned within the cavity of the tube, the wiring harness connecting the accessory and the switch through the opening in the side of the tube;   an accessory at least partially inserted into the inner cavity of the tube,   wherein the switch is configured to actuate the accessory.   
     
     
         11 . The forend assembly of  claim 10 , further comprising a dynamic latch that is configured to connect the tube to the receiver. 
     
     
         12 . The forend assembly of  claim 10 , further comprising a power source operatively connected to the accessory. 
     
     
         13 . The forend assembly of  claim 10 , wherein the accessory comprises a circuit operatively connected to the switch. 
     
     
         14 . The forend assembly of  claim 10 , wherein the accessory comprises a light or a laser. 
     
     
         15 . The forend assembly of  claim 10 , wherein the forend is a pump grip and the firearm is a shotgun. 
     
     
         16 . A shotgun comprising:
 a receiver;   a tube connected to the receiver, having an inner cavity, and having an opening in a side connecting to the inner cavity;   a barrel connected to the receiver and connected to the tube with a lug, the lug encircling the outer circumference of the tube;   a pump grip connected to a carrier and configured to slide along the tube;   a switch mounted to an outer surface of the pump grip;   a wiring harness comprising at least one wire and being operatively connected to the switch, the at least one wire extending through the opening in the side of the tube;   an accessory inserted at least partially into the inner cavity of the tube, the accessory being connected to the wiring harness and being configured to be actuated by the switch.   
     
     
         17 . the firearm of  claim 16 , wherein the accessory comprises a light or a laser. 
     
     
         18 . The firearm of  claim 16 , wherein the tube is connected to the receiver by a portion of a dynamic latch.
