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

A lower receiver for a weapon simulator comprising:

• 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;
• wherein a first output of the first air pressure regulator controls a 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 lower receiver for a weapon simulator comprising:

• a first air pressure regulator contained within the lower receiver with a first output between 50 psi and 175 psi;
• and
• a second air pressure regulator contained within the lower receiver with a second output between 600 psi and 1200 psi;
• wherein the first output of the first air pressure regulator 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.
