Accu-Tac BR-4 Bolt Action Bipod Md: BRB-0400 The Accu-Tac BR-4 Bolt Action Bipod was designed, engineered, and manufactured in the USA. This smaller bipod is convenient for a more grounded shot. The BR-4 is 100% billet, made from the highest quality aircraft aluminum available. Our rail mount is simple, quick, and very secure; it attaches to 1913 Picatinny rail and mounts in seconds. Our leg design allows the shooter to quickly adjust to 5 different positions with the advantage of being able to position each leg differently. To engage or adjust leg position, simply pull the leg downward to move each leg independently. Leg positions can be deployed in a 45 or 90 degree position either forwards or backwards, locking securely into 5 positions through a 180 degree arch.
