I don't know much about Ruger 77's but I believe this to be a stock of the tang safety version of the Model 77 long action. I don't think a rifle has ever been in the stock and it is unmolested except the front sling swivel stud is missing but I can put an Uncle Mike's stud in it which I think is correct for the stock. I have tried to picture every little ding I could find otherwise it is a very nice stock. $150 shipped to your door.
