Help me with Vortex flashhider

BTW, I can't say what's "literally the best" FS. But I can tell you that even the humble little three-prong suppressors from the 1960s M16s work pretty darned well. I have one on a 16" 5.56 upper. I test fired it at twilight once just to see how well it worked. Five shots into the side of a hill and all that was produced were three little blue flames coming off each slot.
