Multi Caliber Lower question

[ar15barrels]

In California.

A person could buy a 50BMG upper, and only put it on the lower when they are out of California; just like 30 round AR magazines.

Sure.

Any clues where to find magazines that will fit the misc other than .223/5.56 for the standard reciever?

What caliber do you want? ASC and C Products make some for 7.62x39 and 5.45x39, I have some of each.

Will the AK type round fit a AR 15 Magazine properly or inproperly...

If so a upper for the 7.62 x 39 mm will operate on a standard ar lower?

Yes, there are plenty of what I refer to as AR47s around. I have one. Lower is nothing special. I also have an AR74, and it uses a fairly standard lower (Magnesium but milspec lower would work fine).

I can't believe this thread has gone this far...really?

Do "Multi Caliber" lowers work for 7.62 or just .223 - 5.56 calibers?
Mag well would have be larger for the 7.62 mags I would guess?

Correct. 7.62 (308 Win) will not work. But a plethera of other calibers will. .22lr, 9mm, 45acp, .410, 300 Blackout, 300 Whisper, 6.5 Grendal, 6.8 SPC, etc. And the 7.62 (AK) round will also work. Those numbers after the "x" mean something.
