Hi folks, I posted this on milsurp.com and think you guys may enjoy trying to figure this one out; I have no idea what's going on and would love some insight.
I got a few years ago this stripped receiver, and never really looked at it until a few months ago. I then noticed that on the right side, there was a "22" lightly etched. I though, that's odd, maybe someone thought it was a weak receiver and decided to label it as only good for .22lr... or something like that.

Then a few weeks ago, I received some parts boxes in which I found a barreled receiver... and on the right side of the receiver, you guessed it, the same "22" lightly etched.

Now, I'm thinking this can't be just pure coincidence. These two receivers are unrelated; they came from totally different sources. But if there is some "official" reason for these markings, well they are really faint, and could very easily go unnoticed. So, dear friends, what's going on here? What should I do with these receivers?
