I’m considering building a lightweight rifle in 6 ARC on a Defiant TiX. Any issues with running a titanium action?

While I'm sure it would be fine, this thread is mostly about building ultralight gasless side charging AR-15 variants. Titanium actions historically have had issues with with high pressure magnum cartridges if any issue was seen. I'm sure a light recoiling low pressure cartridge like the 6mm ARC would do fine in a lightweight Titanium bolt action build but I don't not see the correct bolt face available for the 6mm ARC on the Ti X action. The 6mm ARC is a 0.441" bolt face (same for the 22 ARC, 6mm ARC, 6.5 Grendel, and 7.62x39) and I don't see that size available on their website.

If they don’t have a 6 arc bolt face, might as well go 6 creed.
