Just bought one....Pondering to what extent I might convert it.... What are the legal limitations in Indiana?, Any aftermarket brands that are superior to others?, Etc?

R-W here is a pic of the one I upgraded. Enjoyed building this one. I just recently sold the barrel you see in the pic (A Green Mountain Barrel) nothing wrong with it. Is was a tack driver. Just wanted a different look. I just received a barrel I ordered from Whistle Pig barrel Co.It is a sleeved aluminum fluted 20". I have a Power Customs titanium trigger, bushings,trigger shim kit,bolt buffer. Big Head safety buttons.A Boyds thumbhole salt n pepper stock. I made the bolt lever and the Mag release and polished all the works myself. I will be working on it when deer season slows down. Hope you have as much fun working yours as I did on mine .thanks for listening.
