Rondo,
The H-S Precison bases and rings are really designed for a tactile rifle and to me are on the "pricey" side. The scope base hole are drilled for 8-40 screws. The best bet, and H-S Precison will tell you, go get a set of Talley bases and rings. Be sure to tell Talley it is for a Pro-2000 rifle and that the holes are 8-40. The fixed or light weight will work fine.
