| The “Quick∞Link” Model: Q.R.K. drop-in two-stage trigger system is designed for AK (Kalashnikov) style weapons. This innovative design provides the “Link” between the feel of a crisp 2 stage competition trigger and the rugged durability that has become synonymous with the AK family of rifles. The system is built using precision components that are fully machined from H-13 tool steel. The heat treated parts are then coated with an ultra tough nitride finish. This combination of material and coating will stand up to the grueling environments that are “normal operating conditions” for an AK. The use of the patent pending “Link” system also allows us to incorporate a hammer that maintains a similar design and weight of a stock part. This hammer combined with an O.E.M “braided wire” hammer spring work together to ensure reliable function from a smooth and responsive trigger system. 100% MADE IN THE U.S.A.
