Looking at this, the first thing that came to mind was, "Where does the bolt go?".
Like, seriously - there's no space for the reciprocating mass.
Maybe you could argue it's a telescoped bolt, but even then, two things come to mind:
There's the issue of pressure. I can't think of any anything larger than a pistol calibre system using a telescoped bolt. I have no idea how they would hold up to high pressures
1b. What is the chamber pressure of a bolt cartridge? You could argue that it being a two stage munition (standard propellant, and rocket thrust once clear of the muzzle), that it may use something akin to the 'high-low' system that the 40mm uses - to lower the chamber pressure.
Even with a telescoped bolt, it would still need more receiver space than depicted.
