I’m new to M855 and 5.56 in general. I picked up 140 rounds for $20. Good deal?
That is a great price. Buy as much as you can afford. Where did you get it?
Yeah share your source cause that is bloody great.
Sorry, no source. It was from a friend of mine.
good price.
I got 1000 rounds of Prvi M855 a while back for ~$420 shipped or so.
still have ~900 rounds left 
You robbed him blind!
Seriously, a shop had ammo for that price I’d buy all that they had up to my CC limit.
