I had McGowen do the conversion on my 527 300 AAC Blackout. They built the barrel, accurized the action, installed and re-blued everything. The price was right (~$450 door-to-door), but it took FOREVER! I sent in my barreled action in the middle of November 2011 and I got it back in late May 2012. That's 6 months plus!
I should also mention that I ordered barrel fluting, I paid for barrel fluting and the invoice/packing slip that came back with my new barreled action said they fluted the barrel... But the barrel wasn't fluted. They did give me the option to send it back for them to flute, but I opted to take the refund and not wait another month or more to get it back again.
It did turn out nice, though. They made my barrel to the standard Varmint contour with a 1:8" twist, hacked it off at 16.25" and profiled the muzzle for my suppressor mount (Spike's MRS-2). Here's a picture of it in the Kevlar stock. I have a laminate stock that it'll go in once I get around to pillar bedding it.
