Hello, My friend's son recently purchased a DPMS Oracle. He likes it and it seems to be a great gun. I haven't seen it first hand, but my friend says the firearm is labeled ".308 multi" I'm not sure if this marking is on the barrel or on the lower receiver. I'm not sure what this "multi" marking would mean. I know that the DPMS website states that all the Oracles are chambered for .308Win/7.62x51. Does anyone here have an explanation? I have purchased AR style stripped lower receivers before that were marked "multi-cal" before. Thanks in advance for any information or insight anyone may have on this subject.
