You can buy any old type you'd like! How's that! A company I've used is E.R. Shaw as someone who makes good barrels at a fair price. I also have a custom Douglas barrel on a m98 and it shoots a ton! Simply look around, find a manufacturer that looks good to you and go for it. For the record, I like the looks of a fluted barrel and really like the one rifle I own with one.I just bought a Ruger M77 7MM Rem Mag. I would like to put a fluted barrel on it. Do I have to put a Ruger Barrel on it or can I buy another Brand of Barrel? If any one can answer this question that would be great. Thanks!
