Grumpy Olde Phart  | Go by one of the craft stores, like Ben Franklin. They carry 18 inch pipecleaners. Once you finish with the gas tube, check the rings on your bolt, and security of the bolt carrier gas tube extension. __________________ What we have heah is.... failure to communicate. |

Supporting Member  Join Date: Jun 2010 Posts: 4 | Check the gas key and make sure it is clear… I have seen a blown primer from a bad round get stuck in the gas key and baffle the hell out of everyone… its rare, but it caused FTE really bad… As for your FTF problem… a dirty gas tube wouldn’t cause a failure to fire, neither would a blocked gas key. Any specifics that you can give would help… pics help a ton as well. Factory rife or did you build it? The devil is in the details… have you checked to make sure that your hammer spring isn’t installed upside-down? That causes FTF pretty often due to lighter than normal primer strikes.
