That would be my guess. the CMP is traditionally how fine milsurp rifles made their way into civilian hands. My gun club qualifies under the rules of the CMP so I should be able to get one. And while I’m at it, let me put in another plug for the Appleseed program. No better opportunity to try out that Garand. Turn ammo into skill.
CMP has said they are not involved.
I replaced mine of course, and I wrote the CMP fellows a nice note asking for another WWII vintage if they could manage it (the first was 1942 era and almost 100% Springfield). Well, those boyz sent me a mint 1943-vintage that was all original except for the barrel. Unlike the first one, this second purchase was BLACK with cosmoline -- took me two weeks and a gallon and a half of mineral spirits to get it clean.
Life is good!
