Just wanted to give everyone a heads up, SGammo had about 150 cans of old 5.56 tracer in stock as of 10 pm starting at $280 for 820 rounds (1960s-70s vintage no light), now at almost midnight they are down to 133 cases, they also have 1980's vintage for $320. I went ahead and bought one of the 80's vintage thought it might be fun to play with in my new AR, hey I have to play with the new toy and the 100 or so rounds I bought with it are not going to last long. They also have bulk 7.62x39, etc.
