Comment on Can you scale down a firearm to make an identical looking firearm that fires a different round?
SolOrion@sh.itjust.works 5 weeks agoTo 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.
