The WB-4 Wide Body bipod was designed to provide desired height and extra stability. This bipod style is ideal for long-range, extreme long-range, bench-rest, and for the airsoft platform. The wide, lowered center allows the rifle to sit between the legs which supports accuracy and helps reduce movement from recoil. This is only a suggested use, this model is not exclusive for these applications. The WB-5 is 100% billet, made from the highest quality aircraft aluminum available. This model has the versatility you want in a bipod with its 4 individual leg positions and 5 notch height options. It also has the ability to cant, which can be locked and secured with the adjustable lever. To engage or adjust leg position, simply pull the spring-loaded leg downward to move each leg independently. Leg position can be deployed to 90° or 45°, locking securely into 4 positions. Please keep in mind the cant adjustment lever can be repositioned, DO NOT use a tool to tighten the canting tension. All are black with anodized finish.
