I recently traded some goodies with one of my readers and ended up with this awesome piece of history.
It would appear that someone ordered some spare parts for their AR-180 and then it just sat around, unused.
I believe it was sold recently on GunBroker as a package with the gun and I was able to do some horse trading for it from him.
This is the stuff that really gets my juices flowing. I almost love the history part of this hobby more than the shooting. Almost.
