DPM for Bul Armory SAS II Ultra Light 3,25” Barrel

About the Bul Armory SAS II Ultra Light 3,25” Barrel Recoil Reduction Spring Rod DPM Systems:

The DPM Bul Armory SAS II Ultra Light 3,25” Barrel Reduction Spring 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 SAS II Ultra Light 3,25” Recoil Spring Assembly Instructions

The DPM Bul Armory SAS II Ultra Light 3,25” 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 ULTRA LIGHT 3.25” BARREL

This DPM Mechanical 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 active springs are offering additional buffer to the mechanism, this is a new innovation of DPM Systems.

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