DPM Mechanical Recoil Reduction System for  BUL ARMORY SAS II SL & SL AIR & SAW 5" BULL BARREL - 9 Adjustable User Settings

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 system includes 3 different in length spacers and 3 different external springs. The long spacer offers a heavy buffer effect, moving to shorter spacers a lighter buffer effect is being noticed.

The spacers differentiate only the buffer force (slide full open position) and the external springs differentiate only the slide closed position (slide on the battery).

Detailed instructions for installation also included. 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 position (slide on the battery) according his/hers personal standards.
