Any feedback on barrels from SD Rifles in AZ?

[jrhtx]

The only thing I found here was about 10 years old. Web site doesn't show they sell barrels only now.
Someone local has one they want to move.

FYI it's a 6MM 1:7

Added:
Super fast response from Scott Milkovich at SD Rifles this morning!!
McGowen barrel, stainless steel button rifled, and most likely 5/8x 24.
He said 1:7 was not their normal, 1:8 for 6MM

Specialized Dynamics has a great reputation in the predator hunting community and their new carbon fiber barrels have been producing some tight groups.
