A non-lethal rifle that may include a chamber, a barrel, a gas flow controller that is configured to release, following a trigger, a controllable amount of gas into the chamber; wherein the controllable amount of gas is determined based on, at least, information regarding a target; and an ignition unit that is configured to ignite the gas within a chamber thereby causing a controlled explosion that propels a non-lethal projectile through the chamber, the barrel and towards the target.

Systems and methods are disclosed for a fluid-based projectile launcher having a housing, that may also include a barrel portion, and a propellant fluid chamber. Disclosed embodiments also include a valve assembly that controls flow of propellant fluid from the propellant fluid chamber to the barrel portion through a fluid passageway, and an adjustable block assembly that controls motion and/or position of the valve assembly.

A supplemental propulsion system for a weapon used to fire a projectile includes a barrel and chamber to hold a projectile round. A translating pressure tank surrounds a portion of the barrel, and the pressure tank is configured to translate along the barrel. A recoil spring assembly includes a spring and a pressure plate downstream of the chamber for holding the projectile round. The pressure tank is coupled to the pressure plate such that the spring is configured to stretch upon firing of the projectile and translate the pressure tank along a length of the barrel. The barrel includes a first port configured to selectively align with a first tank port during translation, for the discharge of pressurized gas from the pressure tank. The discharge of pressurized gas occurs rearward of the projectile as it passes through the barrel after firing.

A launcher with a digital range finder that controls the operation of a variable velocity control valve that controls the flow of compressed air delivered to the breech. The launcher includes internal air chamber that fills with compressed air and a restrictor plate housing located on one end of the air chamber. The housing includes a center bore axially aligned with the air chamber. Located inside the center bore is a motorized restrictor plate configured to permit or block the flow of air from the air chamber into the breech. During operation, distance readings from the range finder are processed by a main microprocessor into motor signals that selective rotate the restrictor plate to control the flow of pressurized air and control the distance the projectile travels. In a second embodiment, the launcher is used with a computer controlled ballistic that includes a secondary microprocessor coupled to the main processor that triggers a secondary explosion inside the projectile after being launched.
