Can you scale down a firearm to make an identical looking firearm that fires a different round?
Can you scale down a firearm to make an identical looking firearm that fires a different round?
Like, could you make a smaller version of a 1911 that fires 22lr instead of .45 by just scaling all the parts to the 22lr?

Calibre conversion kits do exist. I think they could be for might be cases where people want to practice marksmanship with smaller calibers like a .22 https://en.m.wikipedia.org/wiki/Caliber_conversion_device
I have an easily swapable bolt that let's my AR-15 shoot .22LR. Pretty nifty, though not quite as accurate since the bullet is .003 thinner.
I have never considered shooting a .22 out of a .223 barrel as a possibility. Very nifty!
Got this one. Only one on the market I know of.

Same bolt came in my Han Solo pistol.
It's worked surprisingly well in the past, but I just put a heavy (H3) weight in to reduce recoil, probably won't cycle .22LR any longer. And BTW, that heavy weight is a dream! My wife's friend brought his stock AR to our camp and I was shocked how much harder it kicked.
I was wondering how the headspacing works. Neat!

To clarify for the OP, these don't generally scale down the whole gun. Caliber conversions can be as simple as swapping the bolt.
You can also sometimes swap to a larger caliber. They make 'conversion kits' for the AR-15 that are functionally just most of a new gun. You can get those for a variety of calibers from 7.62x39 to .50 Beowulf.
