Archery term
Plunger (Button)
What does Plunger (Button) mean?
A plunger, also called a cushion plunger or Berger button, is a spring-loaded pin that threads through the riser at the arrow rest and contacts the side of the arrow. Its spring tension and depth are adjustable to control how the arrow behaves at the moment of release.

Why it matters
The plunger absorbs and corrects the sideways flex of the arrow as it leaves the bow, allowing the archer to fine-tune left-right arrow flight and center shot. Adjusting plunger tension and position is a key step in tuning a recurve bow for clean, consistent arrow flight.
What to check
- Check whether the riser accepts a threaded cushion plunger and confirm its thread standard.
- A plunger is not an arrow rest; a rest does not replace its spring action.
- Contact support for compatible sourcing if your riser manual calls for one.
