It's not impossible - FN is touting a conversion kit to do exactly that for the SCAR 17.

What might be more difficult is to find any of the parts particular to it. You'll need a barrel for the AR10 in .223, a bolt with face sized for it, a magazine well block to fill the left over space, and that holds the standard AR15 mags. Possibly a special mag to just load 5.56, but fits in the same space.

Of all the likely vendors, most already sell the AR10, so that would be the place to start. Don't be surprised, but as suggested, there may not be any conversion parts out there at all. It will require reassembly, and if you want to go back, then changing the barrel out again.

Unlike the SCAR, the AR doesn't just swap barrels out in a minute. Some vendors offer a kit to do that with AR15's, but AR10's lack demand for a lot of small stuff.
