ESS BUTTSTOCK ADJUSTMENT WHEEL FOR FOLDING BUTTSTOCK

Thank you for purchasing the ESS Folding Buttstock Wheel Addon. The following document will go through the installation of these components into your ESS Chassis and Buttstock.

  INSTALLATION

  • Ensure the firearm is unloaded
  • Remove the magazine and bolt
  • Loosen the two thumb wheels on the side of your buttstock to remove the cheek-riser assembly.
  • Remove the cheek-riser from the adjustment plate. To do this remove the screws on the top of the cheek-riser. This will loosen two nuts on the bottom of the plate. Place these somewhere safe, they will be used again.
  • Take the included threaded rod and #10 button head cap screw and attached the threaded rod to the adjustment plate as shown. Ensure the flats machined on the side of the threaded rod are within the machined slot on the adjustment plate.
