They run out of barrels often enough that some folks don't get what they want when they order them, their CS is second to none, but supply doesn't always equal demand, unfortunately. A couple years back, .30-30 barrels were out of stock for 6 months, but for the most part, 8-9 weeks is the longest I've waited or seen anyone else wait for a barrel to become available, I think they're also out of .25-06 barrels right now.
