Hi everyone.

I'm having issues with an assignment that I'm working on, and the first time around it was going well, but then all of a sudden the barrel of the rifle exploded and I couldn't get it back. So, basically, I have been trying to redo it, and now I'm having a different issue. When I extrude it leaves the X while Im pulling back the face to create the inside barrel.

I haven't been able to NOT get an X everytime I do it.

Please help!
