If you can change your breaks, you can convert a siaga. You want something special done, like sbr, or inconel blast chamber, maybe even a top of the line finish. Go pro. If you go pro you can't loose, if you DIY, you'll gain experience, it's easy if you have basic skill sets with tool, not really any serious gunsmithing required, lots of videos for help. But yea if yourself doubt go with Tac47 he's a local guy, and everybody around here recommends him.
