About the DPM for Bul Armory SAS II SL – SL AIR & SAW 5″ Barrel Rod DPM Systems:

The DPM Bul Armory DPM for Bul Armory SAS II SL – SL AIR & SAW 5″ Barrel Rod by DPM Systems replaces the original factory guide rod/spring system and produces an advanced recoil reduction by absorbing the shock gradually and slowing the slide down before its impact with the frame of the pistol. Because the system is an interior modification of your pistol it will not change the external dimensions of the handgun, therefore there is no for a new holster, sights or any other accessory you own.

Bul Armory DPM for Bul Armory SAS II SL – SL AIR & SAW 5″ Barrel Recoil Spring Assembly Instructions

The DPM Bul Armory SAS II SL – SL AIR & SAW 5″ Barrel recoil spring system works due to its multi spring rod design (three springs) by producing an advanced recoil reduction technique by gradually slowing the slide down before impacting the frame of the pistol using Spring No. 1 (see fig. below) and Spring No. 2. The third spring (Spring No. 3) which is contained within the rod itself controls the movement of the slide so it never rams on the frame.

DPM Mechanical Recoil Reduction System for BUL ARMORY SAS II SL & SL AIR & SAW 5″ BULL BARREL

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, a spring plug, a red pressure plate tool, a metallic cup screw tool and 3 different external springs. The long spacer offers a heavy buffer effect, moving to shorter spacers a lighter buffer effect is being noticed.

Washers 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.

*Dimensions of the spring are the same as the original.
