The problem is that carbine-type ARs have an additional problem in that
they have propellant burning outside of the barrel. While I don't claim to
be a firearms expert, I think that having combustion take place inside your
silencer would not be a good thing.

The other effect is that you probably can't bleed propellant gases quickly
enough before the bullet leaves the barrel to prevent acceleration to
supersonic speeds.
