multi-cal lowers

shilowar
Does it matter if a lower is marked multi-cal inorder to use ti for multiple calibers?

Just because it says 5.56 you can still use it for 6.8 or 5.45 correct? or wrong?

    When was the last time you saw a Remington 700 with the caliber marked on the receiver? How about any other common bolt/lever/pump gun?

    It does not matter.

    What they said. The only caveat I would add is, just as bolt actions have short and long actions, you have to stay in the correct class of cartridges. The standard AR 15 will fit 223, 6.8, 7.62X39, 5.45, 9mm, 500 Beowulf, etc while the larger AR 10 type handles 308, 243, 260 and larger cases.

    Legally speaking, yes you can.

    As far as I know, caliber conversions are legal everywhere, so go right ahead and fire .22LR from your .223 labelled AR-15 (or 7.62x39, or 5.45x39, or 9mm luger, whatever). The fact that the receiver is marked caliber "X" doesn't matter.

    At worst, you lose a 'style' point, but if you can live with the "shame" then so be it. [;)][:D]

    Industry standard is the caliber of a firearm is inscribed on the BARREL, since that's the part the bullet actually passes through, and usually (though not always) the the part that contains the chamber.

    For reasons that should be obvious it is NOT a good thing when the caliber label written on the barrel and that of the actual chamber don't match.
