About Trigger Spring, M4
Does your trigger feel sluggish, or are you missing a crisp, instant return when firing fast single shots? The Retro Arms AR15 Trigger Spring is a small but important internal upgrade for your V2 gearbox. This spring returns your trigger to its starting position consistently and reliably, so you are ready for the next shot in a split second.
The right resistance for standard and upgraded setups
Whether you run a traditional mechanical trigger contact or have upgraded to an advanced electronic unit (e.g. GATE Titan, Perun or Aster), the spring tension is crucial:
- Premium hardened spring steel: Made from hard-wearing quality steel that keeps its precise elasticity and constant tension over time. It does not go "soft", even after heavy use on the field.
- Crisp, noticeable reset: The spring balances a comfortable trigger pull with a fast, crisp reset, helping to sharpen your trigger response in semi-auto exchanges.
- High precision: Bent to Retro Arms' tight tolerances, so it sits firmly on the trigger axle without binding in the gearbox shell.
