Rattler

My Magazine won’t cycle on its own. 

  • Loosen the side clamps and thread the barrel all the way until it stops (bottoms out) Then grab the barrel putting your thumb fingernail in line with the side picatinny rail. Turn it counterclockwise (out) until your thumb bumps into the bottle. This will be a very small throw (1/10 of a turn) but usually works here to ensure that the barrel is tight enough to seal on the magazine, but not too tight that it does not allow the magazine to rotate. 
  •  Another possibility is if you are shooting near or below freezing temperatures the factory grease tends to harden up when it gets super cold. 

How do I remove and reinstall the barrel?
