From the experience I had with them 3-4x the quoted lead time is probably more accurate. I was around 18 weeks to have a barrel spun on and another 12 to get a replacement for that barrel due to a not so great chamber job.
Right now I'm just anxious to get my barrel in time for my action, I hoped ordering 2 months ahead would give them enough time. I'll start pinging them when my action is finally ready, but I don't have an ETA for that either. My invoice had the 8/15 ship date, wonder what the hold up is.
