I'm going to have to go +1 on savage's accutrigger. If set up just right, it has a danm good feel to it. I only wish I could adjust the X-mark pro trigger on my remington 7RUM to feel that good.
The McGowen outlet only has already-built pre-fit barrels. If you want a non-run-of-the-mill barrel, like the 32" straight cylinder pre-fit that I just got recently, you have to go to the main site and order it, with 12-15 weeks (currently) lead time.
Geez 32"! What's that going to be chambered in? .338 Lapua?
