Upper receiver device

Abstract

The Upper Receiver Device (URD) is a safety invention to protect a left handed person from shooting a right handed rifle and the hot spent cases striking them in the face, eyes and neck which may cause burns, blindness and other injuries. The left side Upper Receiver Device (URD) is new and an improvement in the left handed rifles. The Lefty URD is different from those used by right handed rifles as you look at them in the right and left side. The bolt lock, carrier of the Lefty URD is different in the number of ridges. The bolt lock, gas hole and the internal components are different and must be manufactured to the Lefty URD specifications.We reference the AR-10 and other rifles with various substitutions and modifications this invention applies to other firearms and is included in this disclosure.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to an apparatus for a firearm attachment. More particularly, the present invention is an attachable upper receiver for a rifle which is especially configured for accommodating safely a “southpaw” or left-handed shooter.BACKGROUND OF THE INVENTION[0002]The conventional AR-10 rifles were designed so that the hot spent, cartridge casings would strike a small deflector rib at the back of what is known as the ejection port and rebounds forward at about 40 degrees. As the rifles cyclic rate of fire decreases; the ejection pattern slowly shifts rearward. At around 700 rounds pre minute, the spent hot cartridge cases miss the current defector rib and spins back almost parallel to the side of the rifle, on the left side with respect to the shooter's perspective. For a right-handed rifleman, this condition is dangerous because the hot spent cases strike them in the face eyes and neck, sometimes causing burns, blindness or oth...

AI Technical Summary

Benefits of technology

This patent describes a new rifle upper receiver that is designed to prevent hot spent cartridge cases from hitting the shooter's face, eyes, and neck areas. It is specifically designed for left-handed shooters, but can also be used by right-handed operators without the need for field adaptation. The invention provides a barrier for fired cases, allowing them to strike and bounce off the deflector and land away from the shooter's person. This improves safety and prevents injury.

Problems solved by technology

For a right-handed rifleman, this condition is dangerous because the hot spent cases strike them in the face eyes and neck, sometimes causing burns, blindness or other injuries.

In one unfortunate documented incident for a right-handed shooter, a burning hot expended cartridge was not deflected properly and rolled inside his open shirt neck, eventually burning his stomach areas; panic-shooting led to the accidental death of one soldier and the wounding of still other soldiers.
