"It's a rifle, not a priceless historical artifact. They were sold by the thousands and for cheap. Many of them are still cheap. While collectors may see a valuable rifle to be kept indefinitely in its original form, lots of other folks see them as the basis for a hunting rifle or a full custom. The bottom line is they are the property of their owners to do with as they see fit"
Boy, do I agree!
My much-"molested" Mosin has done all kinds of wonderful things for me.
It was made in the middle of WWII, probably NOT with that stock, or even that bolt (handwritten numbers) and certainly not with the accoutrements I received with it.
I learned how to shorten a barrel, and recrown a barrel -- accuracy went way up.
I learned how to mount a scope -- my ability went way up
I learned how to stiffen the barrel with a galvanized water pipe -- groups REALLY shrank!
Redid the stock to allow a "foot" for a Rock BR front rest (haven't stained that yet)
Now this $120 relic can reliably hit orange clays at 300 yards, time after time! When I first started, we aimed at a 8.5x11 sheet of paper at 100 yards and hit it ONCE out of about 10 tries.
It is a cheap rifle, made in the millions upon millions, parts scattered all over, and now I'm taking the skills I learned from it and helping as many as a dozen people who are entering our sport. Thank goodness we have liberty to learn from our property!
