The Accu-Tac SR-5 G2 with the Arca Spec Mount was designed, engineered, and manufactured in the USA. The SR-5 G2 is 100% billet, made from the highest quality aircraft aluminum available. Its 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. The SR-5 G2 has the ability to cant, which can be locked with its new throw lever. The quick detach rail mount is simple, quick, and very secure. The quick detach attaches to a standard Arca Swiss or Arca style rail and mounts in seconds without the need to use extra tools for tightening. Accu-Tac's ratcheted leg extension design allows the shooter to quickly adjust to 9 different heights without having to align each leg equally. The spring-loaded leg extension retracts quickly with a one-button retraction lever. The retracted leg height of 6 inches extends to a full open position of 10 inches with 8 other positions in-between. 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 degrees, locking securely into 4 positions.
