    Honestly I’m all for more guns and I could just be amateur hour but if you showed me this picture no caption I couldn’t tell you what special about this rifle or even that it’s new it’s another AR like every one else is makin

      According to the article there isn’t anything special about this rifle. All they did was take a standard CMMG rifle and slap on some popular AR aftermarket parts and call it a day.

    Good to see more rifles chambered in .300 Blackout, though I would like to see more piston rifles with that caliber 😀
