Hey fellers :) I'm looking for receiver tube-"blanks". More specifically, I'm looking for a tube for the venerable Beretta M12S. I saw one at the gunshow today, but they wanted $150 for it ! It was a piece of pipe, threaded on both ends ! It had a shitty template glued to it ! NO WAY it was worth $150 !! Surely some of my fellow hack-smith homiez knows where to find something like this, yes ? Please advise !
