I have M855A1ammunition total of 600 rounds

In original packaging this is a rare and hard to find ammo and on average sells for $3 dollars a round or higher.

I'm only asking for $1.50 a round to the total of

$900 as I'm looking to buy another gun and would like help to pay for it. 600 rounds in total this is the ammo that replaced the army ammunition in 2010 aka m855 green tip and is currently being used now. 

Consider trade for anything CZ but would like cash also
