The Accu-Tac FC-4 G2 F-Class Bipod with the Arca Spec. Mount was designed, engineered, and manufactured in the USA. This F-Class bipod is perfect for long-range, target, competition, and airgun shooting. 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 FC-4 G2 Arca Spec. 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 pan as well as cant, which can each be locked and secured individually with the adjustable lever. The leg design allows the user to quickly adjust to 4 different height positions with the advantage of being able to position each leg individually. The rail mount is simple, quick, and very secure, it attaches to a standard Arca Swiss or Arca style rail, and mounts in seconds without the need to use extra tools for tightening. 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 degree or 45 degree, 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.Features :6061 T6 Aluminum alloy / High strength steel hardwareQuick Detach Arca Swiss MountFour Individual Leg Positions and Five Height Positions,Min Height 5.50" / 139.7 mm ,,Max Height 8.50" / 209.5 mm ,,Min Stance 12.25" / 311 mm ,,Max Stance 16.50" / 419 mm"29.16 ozFlat Black
