Acquiring barrels

I have two questions, what is the best source of Getz barrels?

Does Getz , Green Mountain or Colerain make swamped barrels with twists suitable for conical ( 1 in 48 or faster)?

I'm sorry, :redface: I should have been more specific. The barrel I'm looking for (D. profile, 37 inch for a Edward Marshall style kit). I'm thinking about either 58 caliber or 62 caliber and I would like to go with Getz barrel's or L. L. Rice but I was curious if anyone made a faster twist in a D. profile barrel?

L.C. Rice will do any twist you like. "Any twist option at no additional charge."

He's a nice fella, to boot. Tell him I sent you and he'll say "Wha? Who?" That kidder.
