    I haven't full sized AAC 300 blackout right now running an AAC 7.62 SDN6 and want to get the 9" SBR upper. Where is the best place to find one? Any reviews would help as well.

    You need to acquire an sbr stamp for your lower, get it engraved, then you can buy the shorty upper. Or you can buy a pistol lower for it and run it as a pistol.

    Aac is the best source i would think since its their baby
