I had my pip wrench right next to it the hole time I was trying to unscrew the barrel ... I used a 4 foot barker bar and couldn't get it to brake free so I went to a 6 foot bar and I really had to jump on it ... I did get it off with on scratches at all ... when I looked on you tube then suggested to heat the receiver up 300 degrees and then turn it they said to oil and cleaning solvent can glue the barrels on on older rifles thanks for you comment ...
