TM G18C hammer spring issue
 

Hi,

I'm working on a TM G18c, installing a new hammer spring, and I can't seem to get the part thats supposed to pop up (pressed by the hammer spring) to do so when the trigger is pulled. Everything else seems to be working, but its like the hammer spring isn't putting any pressure on anything?

Do you mean the firing pin?

Did you install the hammer spring correctly? the longer "leg" has to sit on top of the hammer housing. Not inside.

If you are referring to the firing pin, check to make sure you've installed the spring for the disconnector properly...
