    beats me, just wondering. I see lots of lowers marked as "multi" figured there had to be a reason.

    I think that's mostly so somebody doesn't try to load .223 into a rifle chambered for something else.

    I think really the only time the lower matters concerning the caliber is .308 VS. everything else.

    Physically, yes. While it doesn't matter right now, the laws could change and lock that particular lower into one caliber unless marked multi.

    Unless you have to register your rifle :)ugh:) and it's specific as to caliber, the designation on the receiver shouldn't matter a whit. And even then, really, unless the law under which you register it is really anal about only allowing calibers designated on the receiver....which I don't see why they would.
    And I don't know of all that many laws in the US at least requiring registration of non-NFA long guns.
