US12693091 - Drop-in simulator for lower receiver and methods of making the same

Weapon simulators and components for a weapon simulator are provided. In particular, a lower receiver for a weapon simulator is provided. In preferred embodiments, the lower receiver comprises a first air pressure regulator contained within the lower receiver and a second air pressure regulator contained within the lower receiver and designed to supply a higher pressure compressed air than the first air pressure regulator. The first output of the first air pressure regulator controls the second output of the second air pressure regulator. The lower receiver is designed to have the higher pressure compressed air from the second air pressure regulator drive a simulation component.

The patent describes a lower receiver for a weapon simulator that incorporates dual air pressure regulators to manage different pressure outputs for simulation components. This design allows the lower receiver to replace that of a real firearm while controlling compressed air flow for enhanced simulation capabilities.

Claim 1

1 . A lower receiver for a weapon simulator comprising: a first air pressure regulator contained within the lower receiver and configured to convert compressed air directly from a container to a first output between 50 psi and 175 psi; and a second air pressure regulator contained within the lower receiver and configured to convert compressed air directly from the container to a second output between 600 psi and 1200 psi; an electronically controlled solenoid valve: wherein the electronically controlled solenoid valve controls the first output of the first air pressure regulator, which flows through the electronically controlled solenoid valve when activated and directly into a high-pressure valve which controls the second output of the second air pressure regulator; and wherein the lower receiver is designed to have the higher pressure compressed air from the second air pressure regulator drive a simulation component; and and wherein the lower receiver is designed to replace the lower receiver of a real firearm. a first air pressure regulator contained within the lower receiver and configured to convert compressed air directly from a container to a first output between 50 psi and 175 psi; and a second air pressure regulator contained within the lower receiver and configured to convert compressed air directly from the container to a second output between 600 psi and 1200 psi; an electronically controlled solenoid valve: wherein the electronically controlled solenoid valve controls the first output of the first air pressure regulator, which flows through the electronically controlled solenoid valve when activated and directly into a high-pressure valve which controls the second output of the second air pressure regulator; and wherein the lower receiver is designed to have the higher pressure compressed air from the second air pressure regulator drive a simulation component; and and wherein the lower receiver is designed to replace the lower receiver of a real firearm.
