This is just an FYI for anyone thinking about ordering a prefit requiring a large shank, and you wanting a certain heavy profile.
Only one Co. I've talked to told me that an M 24/MTU profile would require a lot of extra machine and have zero gain over a staged or Palma profile.
If you were going to spend close to $ 600.00 for a bbl. wouldn't you want to get what you wanted ?
