I have my fathers Ruger M77-7mm Mag Tang Safety rifle he hunted with. I would like to get a new stock for it and would really like this rifle to look good when it’s done. I was looking at Boyd’s and wanted to know - I see it says drop in but is there any minor fitting with these stocks? Or are they pretty close to OEM? I’d love to find a clean Circassian Ruger factory stock for this gun. But that hasn’t happened.
