DPM Mechanical Recoil Reduction System for BUL ARMORY SAS II TAC & PRO 4.25" BARREL

The DPM Mechanical Recoil Reduction Rod 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 (3 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 external springs are different in length, the long spring is heavy and the short is light so the shooter can fine tune the pistol on the opening and locking positions (slide on the battery).

Within the kit are included 5 different in length and strength external springs, for the 2 gold coated springs their wire diameter is 1.05mm and are softer during the slide travel than the 2 silver coated springs with wire diameter 1.1mm.
