300 AAC Blackout upper
I have been ripping my hair out trying to find either a 9 inch or 16 inch Advanced Armament factory upper. I have seen them on many forums but no one has said where they acquired them. I know that PWS, Noveske, Wilson Combat, etc... all make 300 blk uppers, but I like the one from AAC. Any help would be great.
It is God who arms me with strength and makes my way perfect. He trains my hands for battle; my arms can bend a bow of bronze. You give me your shield of victory, and your right hand sustains me; you stoop down to make me great.
