Gas propelled munitions Anti-fouling system

Abstract

A gas propelled munitions anti-fouling system has a case having an open forward mouth end, a rear end, and an interior, the rear end defining a pocket that receives a primer and a passage communicating between the pocket and the interior of the case, a quantity of propellant received within the interior of the case, a quantity of anti-fouling composition received within the interior of the case, and a bullet having a rear portion inserted into the open forward mouth end of the case. The anti-fouling composition may have at least one salt and at least one acid. The acid may be anhydrous. The salt may be sodium chloride or sodium nitrate. The acid may be anhydrous citric acid. The anti-fouling composition may have at least one abrasive. The abrasive may be stannic acid. The anti-fouling composition may be 50% salt by weight and 50% acid by weight.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application No. 62 / 314,093 filed on Mar. 28, 2016, entitled “GAS PROPELLED MUNITIONS CLEANING SYSTEM (GPMCS),”and U.S. Provisional Patent Application No. 62 / 334,619 filed on May 11, 2016, entitled “GAS PROPELLED MUNITIONS ANTIFOULING SYSTEM (GPMAS),” which are hereby incorporated by reference in their entirety for all that is taught and disclosed therein.FIELD OF THE INVENTION[0002]The present invention relates to firearms, and more particularly to a chemical composition that reacts to produce anti-fouling agents upon discharge of a firearm.BACKGROUND OF THE INVENTION[0003]Modern firearms utilize a brass cartridge containing a primer, gunpowder, and a bullet. A firing pin struck by the firearm's hammer strikes the primer, which in turn ignites the gunpowder. The resulting gas pressure drives the bullet forward out of the firearm through the barrel. Every time the gun is fired,...

AI Technical Summary

Benefits of technology

[0013]There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

Problems solved by technology

Severe fouling can result in numerous undesirable effects.

These include misfeeding of rounds, decreased muzzle velocity, and decreased accuracy.

Salts in the primer and / or gunpowder are also corrosive, which can cause considerable damage to a firearm if they are not periodically removed.

However, this is a time-consuming process that is especially lengthy for semi-automatic and automatic firearms with a bolt carrier group, which requires thorough disassembly of the firearm to reach and remove all the fouling.

Such a round may have many small machined components, making it expensive to manufacture and requiring specialized manufacturing processes that make it unable to be offered for sale at an affordable price.a round having liquid cleaners, such as detergents, loaded into the round.

A segregation barrier is required between the cleaners and the powder because a liquid cleaner would degrade the gunpowder and interfere with proper operation of the round.
