Cage off = normal brakeLol "less gay".
How exactly does that thing work? ... I see holes everywhere.
Cage on = directs majority of concussive blast forward while retaining some muzzle brake effects (hence the holes). It's a hybrid.
The problem with the Witt SME style is that once you put on the sleeve/shroud, it no longer acts as a brake. You can see in some of the youtube videos that the rearward push of the rifle increases with the shroud on. You might say, "who cares it's only 556" but then why spend $175 on a device that doesn't do much beyond a bare muzzle?
