If it is already SBR'd there is no point to the SBX, just go get a 4.5" barrel.
That said, the Sparrow is only 4.75", how long is that shroud?
Clint Beyer can make you a shorty barrel or a shrouded barrel as well, but he can make it exactly to your specs. and you can send him the stuff to put whatever handguard on it you want.
