The stainless steel bore will be slipperier and should allow greater FPS gain from an underbore. Also I think the CF Boomstick has a longer control bore, but I could be wrong.

The Freak back has two front options: The OG Freak front (flared tip) or the All American front (straight tube with spiral porting). They're both part of the Freak barrel system.
