Hey guys, I have rifle getting built off a 1965 model 70 long action. I have not seen this rifle in person (I know, I know) but I'm told it has a big ugly bolt shroud on the first few years of the post 64's. Is this a cover that can be removed or do I need some aftermarket pieces to make it look like the more modern bolt? Just trying to get some info before I call my smith. Thanks everyone in advance!
