Has there been any new guns in .30 super carry
As far as I know Hi-point was the most recent manufacturer to release a gun in .30SC and it was one of their carbines (which I believe makes them the only manufacturer and probably the only people on earth to have ever made a .30SC Carbine besides maybe Federal themselves or some whacko bubba gunsmif)

Two Leader Kits and something you don't see all that often on either side of the current hostilities. A clip on (or rather clamp on) thermal. Usually it's either a dedicated unit or nothing with the exception of Ukr. SF who I would assume have SkeetIR's and VooDoo-S's.

M-60D In Ukraine. Could the DOD not have hit up US Ordnance for a trigger pack or something.

Ranger LAMG.

A few notes
1. This is a Post 2021 model meaning the feed tray that flips to the 3 o' clock instead of the 12
2. First time I've seen one without a buffer tube much less an MCX Stock
"Stingray" FGC-9 in Myanmar. Simply a more bigger FGC-9, much rarer than it's smaller progenitor
Chinese .338 (Norma? Lapua? New Indigenous chinese thing?) MG
Faxon has a new, to say the least, interesting gas block design
I don't know how well moving the gas tube forward and back is going to play
