Stop trying to get your gun to work with your hands. It was designed to be fired using ammunition. The only thing you should use to Hand cycle a firearm is a dummy round(snapcap whatever). Do not use live ammo.

Go out and shoot the stupid thing once and a while. It might actually make the low left thing go away.

Try to understand that a firearm is still a mechanical object and still needs a certain amount of maintenance to function properly. Oil being the number one thing....
