Brass sterling barrel needs love

I think it's a J&J dating pre 2k. http://i915.photobucket.com/albums/a...35271897_n.jpg Also there is damage to the breech end What have I done to deserve this! Also there are gouges on the copper sleeve. Ill get that pic again, it's not working atm. It's this one though Tippman Paintball Guns for Parts or Repair Lot of Three | eBay EDIT it got my sterling. I couldn't believe it either. I thought for sure out would take forever to id it. O got some of the damage out of the end. I got it to shoot paint so thats good. is there anything I can do about the gouges in the copper sleeve? How does one go about rounding out a barrel? Also it's got better than an inch or so less barrel before the threads than my sterling all american. Why is that? I'd doesn't appear to be cut

Doh!
If I had to guess I would say phantom threads... if I remember right and the remaining info is correct that J&J ran some with 60 deg threads instead of ACME threading. Could be some other oddball pump though or even could have been cut off. Was definitely a pump or something with a foregrip as that's what the sleeve was added for.

Since it's messed up, you could potentially have it rethreaded for cocker (assuming there's enough brass left back there) or actually turn it into a slip fit barrel for the SL68 (cut off the back, turn off the threads...) assuming there's enough meat.

I haven't attempted to round out the end. I'm not prepared to go at it just yet. I need more information on the process

ok went for it and got this far i sent a squeegee through it and the hard plastic popped it right back. i used a bbq fork handle as a dowel lol it had the cone shape i was looking for but was too soft to be of any use. right now it breaks 4 out of ten balls. the other sterling barrels ive seen have another inch or so of metal past the threading and this one does not. was there ever 2 different versions of this barrel thread style? how do i finish making this barrels end round? thanks

Get a hard oak dowel of right size or spin one down. Then press it through from the muzzle. Hardened steel would be best but more difficult to make.

Try using a shooter marble or a 12gram
BTW THAT BARREL IS NOT FOR THAT Sl68 MARKER
