OK, it's frustrating.
Consider this good practice for dealing with custom gunsmiths! Now that can be an exercise in frustration! In my case, I am mystified how I will always, and I do mean always, get a estimated date that is absolutely nothing like the actual delivery date. I've been told 3 weeks and six months later I'm still waiting (Clark Custom), I've been told 3 to 4 months and the gun arrives three weeks later before I've got all the money to pay for it (Rock River), I've been told one week, and two months later I stop in to inquire and they had it done on time, but never called me (the local guy). The latest was where I was told four weeks and 9 weeks later I'm still waiting (Marvel).
I really don't care so much about the time, I care about the expectation of a date range. If they were to tell me it would be six months and it actually is 5 to 7 months, I wouldn't care a bit. It just irks me when people who know what their production pipeline looks like can't give me a reasonably accurate date.
It's endemic to custom gunsmithing.
