Just to emphasize what a few others have said: it's a wonderful rifle to work on. It's great out of the box, but tuning it down is actually a lot of fun, and requires very few tools. I tuned mine down to about 12.5 with a 4600 spring (I think that's the number) from ARH, and some custom made delrin top hats and washers. Someone mentioned the need for a thread on the end of the barrel for a moderator. I agree--no reason for AA not to do that. In the meantime, though, you can get N. Clague to make a moderator that will slide over the barrel. Mine works like a charm, and makes the PS very backyard friendly. Great review of great rifle.
