Exactly. Now there are a few aftermarket options out there, but no full kits like the Freak. Lapco makes a good barrel, and they have options in both .690 and .686
Do remember that if you plan on getting the First Strike conversion for the Tiberius, it requires a modified barrel. The conversion kit comes with a new barrel, but an aftermarket barrel may not work with out further modification. If you're not going to get the First Strike kit then don't worry about it.
