It can be common for the tension knob to be stiff from the factory. To loosen:

  1. Install the bipod on your unloaded rifle
  2. Turn upside down or rest on buttstock with muzzle up
  3. Deploy the bipod legs in the 90 degree position
  4. With both hands on each leg, twist to work the Pan feature side to side

After use, it should start to loosen up. If stiffness is still unsatisfactory, Contact Us.
