Peter Dobson at Hirsch Precision has these stocks in stock.
I have had the opportunity to check them out, and test fire a new build. There were also some shooters at Raton shooting these stocks as well.
They are very well built, and a very rigid shooting platform. They shoot very well from the bench, and we produced some very good groups with factory Lapua ammo. We did actually bed the action, as opposed to the factory instructions and it seemed to shoot exen better with the limited testing done.
The only down side, in my opinion, is that they are fairly heavy. Most F-class shooters are going to bigger, and longer barrels and optics, so total weight is becoming a concern especially in F-Tr.
