Yes saint victor 5.56 lowers will support any .223/5.56/.300BO & Grendell uppers.
I swap a 6.5 grendell upper onto my 5.56 Victor all the time
Victor 5.56 will not support 6.5 creedmore, .308 or other large caliber.

Don’t forget 6.8 SPC and .224 Valkyrie in calibers supported by the 5.56 lowers.

Thanks for the information, I was looking at a .300 blackout upper.
You won't have any problem with a .300blk swap and you can even use the same BCG as the 5.56 interchangeably. If you can find ammo for the .300blk at a reasonable price buy as much as you can afford because its getting harder to find then 5.56 or .223 at least in my area.
Below is a link for reference to what cartridges the AR-15 lower can accept.
There is also a section for AR-10 compatible calibers if you have interest in that platform.
