I hate working on these guns, too many little parts!!! And why is another question :rolleyes:
So, I made "sleeve." to act as the connection point. Then turned the barrels to be a slip fit with the sleeve. The transfer port holds the sleeve in position. After fitting the barrels I spot drilled a locater 90 degrees from the transfer port to locate each barrel.

I finally finished with this project. The 10" barrel wouldn't allow the mod to screw on, so I made a Delrin adapter 1.7" long. I turned barrel down and made the od of the adapter the same 0.44" of the barrel, then pressed it on. It now fits in the front barrel band. I also made him a knurled knob with an M4 stud so the folding stock can be removed without tools.
