Best arca bipod in my opinion - ACCU-TAC Br-4 G2 Arca Spec Qd Bipod

Tops in durability and extremely stable, a bit heavy and expensive however, you get what you pay for. This bipod will out last your life time. I think and hope it does mine. Get it and forget about it. It's the only one you'll need. I have three (2 ARCAs and 1 picatinny). You want a tough worry free bipod? Get an Accu-Tac! Just my 2 cents.
