I wouldn't waste your money on the GRS stock. I had one on an Anschutz rifle. It's heavy and has a lot of crazy angles around the grip and is not conducive to good accuracy IMO. I would get a Crown with one of the other laminates.
Not sure if the GRS stock on the Crown is identical in configuration to their stock on the Anschutz, but I will offer a contradictory viewpoint that the Crown with GRS stock is absolutely the most stable platform
for me on the bench. And I have other Crowns with laminate & walnut stocks, and have had them with synthetic stocks in the past.
The only issue I see with the Crown GRS is that the reach from the grip to the trigger is long. Even with the trigger adjusted back, it might be too long for some folks. For my large hands it is just fine.
My GRS Crowns are more accurate
in my hands than my standard Crowns. But stocks are such a very personal thing. Personally, I felt immediately comfortable on the GRS Crown.
As far as noise, a lot is related to efficient air use. The Wolverine HP uses the efficient Harper Slingshot valve. The RAWs in stock configuration are pretty well known for wasting air (this doesn't impact their accuracy and consistency, but they like to be tethered for a longer shooting session). Wasted air = more noise.
I would say that the Crowns are as quiet or maybe just a little quieter than the Wolverines. Want really quiet accuracy - then you need to be very efficient with air. In my book that equals Red Wolf.
