DPM Mechanical Recoil Reduction System for RUGER MAX-9 3.2'' Barrel

This system works due to the multi spring intricate rod (3 springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.

The system includes 4 external springs, 2 x 1.05 mm wire diameter and 2 x 1.15mm wire diameter, all with different power rates.

**As we lead the evolution of recoil reduction technology, products may change versions (new design with different springs, with or without plugs, washers, etc.) without any prior notice.**
