Frequently Asked Questions
What makes the FD series different from other Accu-Tac bipods?
The fast-deploy spring-loaded legs move from stowed to shooting position in one motion, so it is the quickest Accu-Tac bipod to set up mid-stage.
Will it fit my rifle?
Yes, it clamps directly to any standard Picatinny rail section on your forend — no tools or adapters required.
How is this different from the FD-5?
The FD-5 is the taller version (8–10.75" at 90°) for positional and barricade work; the FD-4 is lighter and sits lower for prone stability.
