Looking for some help with my original SBE. I have shot many thousands of rounds and the gun has been extremely reliable. I have a sure cycle and replaced the extractor a couple times but no problems with the gun. Recently it started not firing on a second or third shot. It is intermittent happening. After the shot sometimes the next shell will load, the bolt will be rotated completely closed with the new round in the pipe. If I pull the trigger again, nothing, not even a click. I can’t tell if the firing pin is not cocking back or if it is stuck in the cocked position. I have noticed the lifter is locked down meaning I can’t push it up and load another shell in the magazine tube. What part is malfunctioning or worn and needs replaced?
Thanks
Zach
