Internal Regulator
Overview
An internal regulator is a pressure regulating component built directly into a marker’s body or bolt system, designed to stabilize air delivery and control operating pressure.
Key Points
- Regulates incoming air pressure within the marker’s internal system.
- Improves consistency, efficiency, and shot to shot stability.
- Found in many modern mid and high end electronic markers.
- Reduces reliance on external regulators and hoses.
- Requires maintenance to avoid creeping or pressure drop offs.
- Can be paired with external tank regulators for dual stage regulation.
Details
An internal regulator is built into the marker’s body and manages the pressure used to cycle the bolt system. It receives pre regulated air from the tank regulator and steps it down further to a consistent operating pressure. By ensuring stable internal pressure, it improves velocity consistency, smoothness of shot, and overall efficiency.
Many modern markers especially those designed for competitive play use internal regulators to lower operating pressure, reduce recoil, and increase shot smoothness. Low pressure operation also improves paint handling, reducing barrel breaks and chops with brittle paint.
Internal regulators require periodic lubrication and replacement of O rings. Symptoms of regulator issues include velocity spikes, drop offs, first shot drop off (FSDO), or inconsistent cycling.
Dual stage regulation (tank reg + internal reg) gives markers more refined control over airflow, improving reliability across temperature swings and high rates of fire.
Internal regulators represent a key advancement in marker engineering, enabling smoother firing signatures and improved consistency compared to early mechanical systems.
