Can someone tell me a little bit about these rifles. I did a search on yahoo but came up pretty much empty. I have one that I inherited from my dad, but its been sitting in my safe for ~15 years and I'd like to strip the bolt for a good cleaning. The machine work seems a bit rough. Sometimes it has a problem ejecting empty shells. The stock has no checkering on the forearm, but does at the grip. I have a set of mounts, but bolt clearance is still an issue. Thanks in advance.
