I have a friend that is have some financial problems and asked me earlier today if I want to buy a rifle from him. It is a Savage 11 Predator hunter in .243. He says it has about 15 rounds through it. It has the accu-trigger and the heavy varmint barrel. It looks brand new. He wants $300 for it. I don't know a whole lot about Savage's. Are model 11 parts interchangeable with model 10. Like stocks, triggers, etc. I can't find a whole lot of info on model 11's. I am thinking about picking this rifle up and building a semi-custom for my son but I want to make sure that parts are available to do so. So any help from you savage experts would be greatly appreciated.
