Yes, it has value. And is useful. It is the proper way to test for feed and function with an AR platform or even a bolt gun. It would also have some collector value to folks who have that interest as it is seldom seen (at least outside of the military and manufacturing facilities) As to the value? My guess is that it is worth at least a buck a round. (probably more) I would, maybe, put it on the WTS board and see if there is any interest. HTH GB
