Firearm Pre-Muzzle Lead Emission Containment Device

Abstract

A device for limiting, controlling, and disposing of lead particles released from a firearm's openings and leakage areas rear of the muzzle. The device is composed of a cylindrical clear polycarbonate enclosure mounted on an aluminum frame which encloses the firearm and the shooters hands. A small opening at the rear of the cylinder allows the firearm muzzle to discharge the projectile. A restricted opening at the front of the cylinder allows the shooter to place hands and firearm within the enclosure. The clear Polycarbonate provides light entry and visibility while affording the shooter some protection against a malfunctioning firearm. The enclosure is under negative air pressure in relation to the environment outside the enclosure. The negative air pressure is provided by either the bullet retention system that the device is mounted to or separately by a connection to a commercially available High Efficiency Particulate Air (HEPA) filter vacuum.

1 . A lead particle emission containment and disposal device for firearms releasing lead particles rear of the firearm muzzle, comprising:
 a clear impact resistant cylindrical enclosure supported by a metal frame large enough to accommodate a firearm and the shooters hands;   a connection to a HEPA filtration vacuum capable of maintaining the enclosure under negative pressure;   a flexible material for restricting entry to the front of the cylinder;   a small opening at the center of a metal cap at the rear of the cylinder for placement of the firearm muzzle;   an energy absorbing cloth mounted within the cylinder to arrest ejected bullet casings.   
   
   
       2 . A lead emission containment and disposal device according to  claim 1  wherein the device also contains and disposes of combustion smoke, heavy metals, and other potential hazardous by-products released rear of the muzzle during the combustion of various manufactured projectiles and propellants. 
   
   
       3 . A lead emission containment and disposal device according to  claim 1  wherein the device also provides additional protection to the shooter's torso and head from flying debris resulting from a malfunctioning firearm.
