Accu-Tac Twbb-0400 Wb-4 Bipod Fde
The Accu-Tac WB-4 Wide Body bipod is a precision shooting rest built for shooters who demand rock-solid stability at the bench, on long-range courses, or in extreme long-range competition. This FDE (Flat Dark Earth) bipod uses a wide, lowered center geometry that lets your rifle settle naturally between the legs—a design that reduces unwanted movement and supports consistency shot after shot. Whether you're dialing in at 100 yards or pushing distance, the WB-4 gives you the control serious shooters expect from a billet aluminum platform.
Built from 6061 T6 aluminum alloy with high-strength steel hardware, the WB-4 is engineered to last through years of hard use. The quick-detach Picatinny mount clips to any 1913 rail in seconds with no tools required, so you can swap it between rifles or stow it fast. Four independent leg positions and five height adjustments let you dial in the exact stance and elevation for your setup. A cant adjustment lever locks and secures the cant angle, giving you control over left-right tilt—just hand-tighten the lever; no tools needed.
Deploying each leg is intuitive: pull the spring-loaded legs downward to move them independently into 90-degree or 45-degree positions, with secure locking at each detent. At 22.08 ounces, it's substantial enough to absorb recoil without being unwieldy. Height ranges from 4.5" to 7.5", and stance spreads from 10" to 14", so you'll find a configuration that works for your shooting position and terrain.

Frequently Asked Questions
Will the WB-4 bipod fit my rifle?
The WB-4 uses a quick-detach Picatinny (1913) mount, so it will work on any rifle or handguard with a standard Picatinny rail. It attaches in seconds without tools.
What's the height range, and will it work for prone shooting?
The WB-4 adjusts from 4.5" to 7.5" in height across five notch positions. That range covers bench shooting, kneeling, and field positions. Prone shooters should verify the height works with their specific setup before committing.
Can I adjust the angle of the bipod side-to-side?
Yes. The WB-4 includes a cant adjustment lever that locks and secures the angle for left-right tilt. Hand-tighten the lever to secure it; do not use tools to adjust the canting tension.
How do I deploy and lock the legs?
Each leg is spring-loaded. Pull a leg downward to move it independently into either a 90-degree or 45-degree position. The legs lock securely at each detent point. You have four different leg-position configurations to choose from depending on your shooting stance and terrain.
