I know for a fact it is 5.56
comes in a 25 round box, I got it from james at the show about 2 years ago...
I know that my other buddy (he is a cop, but the guy he gets it from sells to anybody) gets it someplace in Mukilteo...
I will find out what the scoop is, and let ya know.
but like I said, there is no law that says you have to be a LEO to get it...
Now my big question to you...
Why are you so bent on the 5.56 over the 223?...( a small addition in FPS, but I would rather have a good bullet in 223,over a under fragging round in military 5.56).
I have both, and to be honest I like the 40 gr 223 out of all of them in my 14.5 carbine...( I know that is a varmit round, and not really made for anything over 60 lbs, but it frags like a madman and Im thinking short range headshot type situations).
otherwise Im just go with blackhills in the higher grain rounds.
