Considerations & Trade-offs

  • Ambidextrous setup adds flexibility, but it also means choosing and configuring the lever style that best fits your shooting hand and controls.
  • The selector is described as compatible with all known AR-variant lower receivers and triggers designed to work with the platform, but fit should still be verified against your specific build.
  • This is a duty-grade, professional selector for AR-15/M4/M16 machine-gun use, so it is not a universal part for non-AR platforms.
  • The standard and short levers are modular and interchangeable, which is useful for customization but adds another decision point during setup.
