Accu-Tac's SR-5 Bi-pod was designed, engineered, and manufactured in the USA. It is made from quality aircraft aluminum available. The wide stance and ratcheted leg extension gives you the adjustability needed for precision aim and repeatability. You will feel the stability and security of your rifle as never felt before. Its rail mount is simple, quick, and very secure; it attaches to a 1913 Picatinny rail and mounts in seconds.
