Again, what has "No Collector Value" today, may not have "No Collector Value" even next year.
Two years ago, Soviet Capture K98s were available all over the place for about $200. Now, when you can find them they are about twice that.
Ten years ago, Swede Mausers were going for $99 for a M96 and ~$125 for a M38, retail. Now good examples of either are going for $500.
The newest WW2-era rifles are 67 years old, and they aren't making any more.
If you want to pimp out your milsurp, do yourself a favor and keep the parts, and don't do anything that can't be reversed.
Or leave it alone, and take it out and shoot it. The Sacramento Valley shooting center has Vintage Military silhouette matches monthly, and Long Range Milsurp matches every couple months, out to 800 yards. Hell, I shot a 3-gun match with my K98, in the rain.
Yeah, safe queen.
