The Accu-Tac PC-4 Arca Spec QD bipod was designed, engineered, and manufactured in the USA. This PC bipod is perfect for tactical, target, competition, and airgun shooting.  This is only a suggested use, this model is not exclusive for these applications.  The PC-4 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. Our quick detach rail mount is simple, quick, and very secure; it attaches to an 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° 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.
