DPM Mechanical Recoil Reduction System for BUL ARMORY SAS II ULTRA LIGHT 3.25'' BARREL

The DPM Mechanical Recoil Reduction System is a direct replacement for the stock recoil rod and does not change the configuration of the pistol.

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

The KIT includes 4 different in length and wire diameter springs along with the DPM Mechanism.

The external springs are different in length and tension, the long spring is heavy and the short is lighter so the shooter can fine tune the pistol on the opening and locking positions (slide on the battery) according to his/hers personal standards.

The 2 soft springs have wire diameter 1.1mm and the 2 heavier have wire diameter 1.15mm.
