Overview:
Best Lubes for your G5:
  • Dow33, Violent PB Jelly, Monkey Poo, Lurker Lube, TechT Gun Sav

Between Games:
  • Clean your barrel

  • Wipe down the outside of your marker

  • Remove the back cap and bolt and wipe them down to remove any lube or debris. Next, inspect the o-rings on the back cap for any visible damage and replace o-rings if needed. Before reinstalling, lube the o-rings on the back cap with a small amount of Dow33. Be sure to put a small amount of lube on the 2 internal breach/body o-rings that come in contact with the bolt, found inside the breach. If you do this, you do not need to put lube on your bolt.
