ERMES Double Roller Wing Trigger Mechanism

ERMES Double Roller Wing Trigger Mechanism

The Ermes Double Roller Wing Mech is by far the smoothest, strongest mechanism we have come across. It is made with a patented system, the operation consists of two rollers. One works in contact with the trigger and is constrained to the coupling lever, while the second roller in contact with the shaft is constrained to the box with a pin and is free to move in an oval hole.

This system stabilizes the shaft at the moment of firing. The load is evenly distributed, decreasing friction. Will accept 9/32nd or 5/16th American notched shaft and 7mm, 7.5mm, and 8mm euro shafts.

Three versions available:

  • Large Double Roller (Silver)
  • Large Double Roller (Gold)
  • Short Double Roller (Silver)
