The Quadra is the top model of JT. It is characterized by first-class processing and a spectacular design. An enormous amount of features, like the dual-ball detents, the Delrin anti-chop bolt and -above all- the standard infrared anti-chop eye, let ball breaks belong to the past. Also the other parts are unmatched. A fully adjustable front regulator provides for best constancy at the chrony station and the multi-function display lets you always keep the overview. A further plus is the "Gorilla Grip", an innovative clamping feed, which holds the hopper, where it belongs to. The three ways adjustable trigger and the ergonomically formed 45 grip provide for perfect handling.
