I have had a lot of good luck with a couple of rests.
First, I really like the Sinclair bipod. It works really well and is pretty easy to adjust and work with.
Second, I like the front rests built and sold by Grizzly Industrial.
They both are really well built and worth the money. I figure you can't get a better rest without spending a whole lot more. And they both are a huge step up in performance from rests that are at the next lower price level.
Not dirt cheap, but one step away from cheap.
I don't think you can go wrong with either one.
Then, get a decent medium to heavy rear bag. Too light is not your friend. I like the Protektor bags. They aren't too pricey, but they work. You can find them at the Sinclair website or at Graf's.
Good luck.
