The Accu-Tac SR-5 G2 Arca Spec QD Bipod was designed, engineered, and manufactured in the USA. The SR-5 G2 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 SR-5 G2 Arca Spec QD 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 9 notch height options. It also has the ability to cant, which can each be locked and secured with the adjustable lever. The leg design allows the user to quickly adjust to 9 different height positions with the advantage of being able to position each leg individually. The rail mount is simple, quick detach, 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.
