Looking for a budget bipod and possibly at a rail for my Ruger Precision rimfire. I plan on using it for NRL22 and the likes. Can anyone recommend a budget bipod maybe sub $100 for the bipod. Plus any recommendations on weather or not I should add an arca rail?

Get a Harris swivel head, and be done with it. You`ll save money in the long run. BTDT.

^^^^^ yep take it from me you end blowing more money on cheap bipods when in the end you could of saved money and bought a high end one from the get go.
