Is there somewhere to get a brand new threaded barrel?  Basically I am looking to do a full new build on a milled firing line reciever.  I want to use a threaded barrel, but am not sure who makes them.  Does anyone know who builds barrels for threaded barrels?

unless you talk to a custom barrel maker ,, your only option is to find a good type II or III kit
the Russians were the only ones who made threaded recievers...  
another option is to find a press pin barrel and have a threaded sleave made up that you can press in  and pin .. then screw the whole thing into the reciever..

I have a used russian "PLO" barrel I was going to build on a firing line receiver.  Talking to firing line if I send them my barrel and bolt they will install it and headspace it on their under folder threaded barrel receiver for $650.  I have a brand new underfolder stock parts set to go with it But I am thniking of canceling the idea and building 5 more romy "G" guns for when my kids get older.

If you are interested in my parts send me an E-mail and I can send you pics and tell you what I know.
