Abstract

A system and method for a modular, low lethal projectile is provided. The modular, low lethal projectile system comprises an exterior shell, propellant cartridge, and a projectile assembly. A propellant mounting area is arranged at a rear end of the exterior shell and is offset from a center of the exterior shell. A propellant cartridge is secured within the propellant mounting area. A firing pin of a firearm is configured to strike an edge of a cartridge primer of the propellant cartridge, which ignites a primer material and propellant within the propellant cartridge. The resulting hot, expanding gasses propel the projectile assembly form the firearm, and upon contact with a desired target, the capsule tube of the projectile assembly breaks, distributing an effective compound into the air around the desired target.

Claims20

Dependent claims

A system for modular, low-lethal ammunition comprising,

an exterior shell having a first internal cavity accessible via a first opening on an expulsion end and a second internal cavity accessible via a second opening on a rear end,
wherein said first internal cavity and said second internal cavity are separated via an internal structure,
a projectile assembly comprising a capsule tube and a sealing member,
wherein said capsule tube is configured to hold an effective compound,
wherein said sealing member is configured to secure to an aperture of said capsule tube in a way such that it seals said effective compound within said capsule tube,
wherein said sealing member creates an expansion chamber with said internal structure and walls of said exterior shell when secured within said first internal cavity, and
a propellant cartridge comprising a hollow casing, cartridge primer, wad, primer material, and propellant,
wherein said hollow casing is configured to be inserted into said second opening of said exterior shell,
wherein said propellant is configured to deflagrate into hot gasses that expand into said expansion chamber and create pressure behind said projectile assembly,
wherein said pressure ejects said projectile assembly from said exterior shell.
