I'm reading about other cartridges, and trying to find out which ones require ONLY a barrel change from an AR in 5.56?  I know 300BLK, but what about 6.5 or 6.8?  Those look a larger diameter.

Both of those (6.5 & 6.8) require a bolt change. 204 Ruger only requires barrel change. The Sharps 25-45 only requires barrel change. Basically anything that uses the 223 Remington as the parent cartridge just needed a barrel change.

why just a barrel change?
isn't it easier to pop two pins and change the upper?

besides, then your options open up to bigger stuff, like .458 SOCOM, .50 Beowulf, and .50 BMG

Agreed. Plus scope stays zero.
