I have a chance to purchase the above refernced firearm at a decent price, It is the blue verson with rifle sights and the Mauser style extractor. I was going to make it a "project gun ",blueprint the action,glassbed etc. A friend says the early Rugers had barrel problems and the newer models have fixed that. I have not fired the rifle, but am interested in the proposition. What do you think. Thanks in advance for your comments.
