look at this gun lmao

What round does it take? What company was it made by? Is that thing (circled in attached image) part of the barrel or is it some sort of muzzle brake? Is said circled thing removable? Is that some sort of standard bayonet or is it custom?

I think it's the muzzle

Wait, is this your picture?

no
