If you are looking to use that factory bi-pod that came with your rifle that is just a little too high for the shorter bags made by Caldwell, this might just do the trick. I found with my HK SL8-6 that is was just about the perfect hight for my factory bi-pod. However, there is no adjustability with that set up. Thus it is not a great marriage of the two. However, if you have the larger front rest for the Rock stand it is tough to beat. Great stability and good trigger access.
Pros: Great rest position and trigger access
Cons: Needs high front stand
