Abstract

An assembly for modifying an automatic firearm such as a carbine rifle to relocate operation of the firearm charge handle. The assembly includes a fore-grip bracket, a drive rod movable in the foregrip bracket and attached to the charging handle release lever, and a cocking handle attached to the drive rod, the rod being attached to the charge handle for alternately releasing and latching the charge handle for clearing the firearm. In one embodiment, the foregrip bracket is attached to a removable rail attached to the foregrip by a jaw type device. Another embodiment attaches to the foregrip by attaching the foregrip bracket by screws. Another embodiment attaches to a foregrip having no rail by means of a groove cut in the grip, having a pair of spaced apertures into which hooks of foregrip mount, the bracket being held in place by a rod receiver and rotatable latch.

A charging handle operation system for a firearm comprising:

a foregrip bracket having a mount for attachment to the foregrip of a firearm;
said foregrip bracket having a bracket sleeve connected to and supported by said foregrip bracket mount;
an operating rod having a front end portion and a rear end portion, and coaxially extending through and rearward of said bracket sleeve;
and
a rod connector connected to said rear end portion of said operating rod for connection with a charging handle;
a cocking handle connected to said operating rod at said front end portion thereof;
said bracket sleeve of said foregrip bracket defining an elongated cocking handle operating slot along the length thereof opposite said foregrip receiving said cocking handle for movement of said operating rod between a rest position and a rearward position;
whereby, upon the user grasping said cocking handle by the user's foregrip hand and pulling said cocking handle to said rearward position, said rod connector unlatches and moves the charging handle to a rear, open position;
and
whereby, upon the user grasping and pushing said cocking handle by the user's foregrip hand to said forward position, said rod connector moves the charging handle to the forward, latched, closed position.
