The Accu-Tac 17S Spec-4 Bipod Black is a US-made billet aluminium rifle bipod, part number 17SS-0004, with the 17S Spec mounting interface. It is built on the Accu-Tac BR-4 G2 platform, with height from 5.12" (133 mm) minimum at 45° up to 6.62"–8.12" (165–203 mm) at 90°.
How It Compares
This is the Accu-Tac BR-4 G2 chassis rebuilt around the 17S Spec mounting interface, so it takes 17S Spec accessories rather than a fixed Picatinny or Arca clamp. The Accu-Tac 17S Spec-5 bipod is the other size in the pair. If you would rather have a conventional clamp, the Picatinny QD version and Arca-Spec QD version cover the same platform. Compare the full Accu-Tac range and all shooting bipods in stock.
