Abstract

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.

Claims (12)

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.

2 . The lower receiver for a weapon simulator of claim 1 , wherein the simulation component is a bolt assembly.

3 . The lower receiver for a weapon simulator of claim 1 , wherein the simulation component is a recoil simulator.

4 . The lower receiver for a weapon simulator of claim 1 , wherein the first output is about 150 psi.

5 . The lower receiver for a weapon simulator of claim 4 , wherein the second output is about 900 psi.

6 . The lower receiver for a weapon simulator of claim 4 , wherein the high-pressure valve is pilot operated valve.
