I found an original GI for you, if that holds any value to you.

That's not proof that it shoots well. You should send it to me so I can extensively test it over the next 12 to 24 months. Of course, you will need to supply me with a monthly case of ammo while I am testing out your rifle.
But I thought this was the joke of the day thread.
Just wait until I start sending things for Susan and me. π I hope I can send some ammo, but I don't know if it will be available at a reasonable price.
