Some of take a slightly different approach
I guess according to some folks, I am going to hell. I ain't gonna lose any sleep over it. I have converted, or assisted in the conversion of quite a few "milsurp" rifles, Mausers, Springfields, Arisakas, even Krags. At the time they were as cheap and plentiful as the eastern bloc rifles are today.
Not "bubba-ed", but fine wood stocks, custom metalwork, blueing, etc. Rebarreling, custom triggers, the works. These rifles were not "butchered" they became functional works of the gunsmiths art.
Many people today think that is something disrespectful. I look at it the other way. The rifles are improved, often drastically. These rifles are not really popular right now, and can often be found at the gunshows at near bargin prices.
I also collect and shoot military rifles in issue condition. There is a great before and after thing there. I have a number of milsurps, and no plans to convert any of them. Not because of the money, or because of their historical significance, but just because I have no reason to.
I have a good friend who does just the opposite, when he can. He finds the "bubba-ed" guns, and restores them. We get a kick out of comparing, an issue 1903A1 Springfield (his) to mine, which is a .25-06, custom wood, deep luster blue and polished steel, etc.
Perhaps part of the current desire to preserve milsurps is because most of the best ones are gone, and civilian rifles are better then the used to be. When we sporterized k98s, 1903s, 1917s, and others, we wound up with a rifle equal to or better than what was available from major US makers, and often at less cost.
Those days are gone, and the cheap common milsurps available today
cannot be made into the same class of rifles. Nice guns, yes. But not the quality sporters of yesteryear. I don't mean to upset some of the kids out there who think their M 44 carbine is the greatest thing ever, but you just can't do the same things to it that we did to make our guns. Not and get the same results. You put enough work into a 98 Mauser, or a Springfield or the Enfield, and you can match the high grade guns that came out of Griffith & Howe.
