The QD system, a hybrid by design, took the Quick Adapt Technology from our Hunter Series and put it into a versatile shooting system.  The QD does more than simply function as a barrel rest.  By attaching the QD directly to your weapon, you are able to maintain a proper shooting position giving you control, maneuverability, and stability, unlike conventional shooting sticks. The QD system allows men, women, and children of all levels of experience to have more confidence in the field.
