The brass tube is leftover material I had from when I made a barrel for my A-5 backup gun. The ID is .684 and it works great. I think I'm going to mic the OD of the tube and ream the receiver to match and make it permanent.
Yes the tube is 3ft long
No I'm not going to leave it that length. I think 12-14" is enough.
