Some tools really help me with my accuracy. I love bipods.
The Picitinny based, quick detach, bipods that are currently available are really good quality for modest cash.
My Savage 110FP does not have any Picitinny rails on it so I installed a bipod via a swivel stud mount. The bipod was easily convertible, and quick to install. It makes my shooting so much better.
I don't recommend adding them to every rifle in the safe. They add a lot of front weight if I am not actually using it and it's just folded up.
