Blackhawker,
The program appears to be a crap shoot. I sent my receiver to H&R in late June for a 22-250 barrel. I called ahead of time and it was available, but when they got to my order it was not. They got to my order in about a week so that is good, but they still do not know when a barrel will be available. As a matter of fact, they were due in late August but did not show up.
I think you can expect a really good return time if they have the barrel, but if they do not, who knows? As of Friday August 11, they had no clue when the 22-250 will be available.
Good luck,
Clayton
