DPM Mechanical Recoil Reduction System for SAR K2 45C 4.2? Barrel 4 Adjustable Settings

The US patented recoil reduction system works due to the multi spring intricate recoil rod (3 different energetic springs), controls the functionality of the pistol and replaces the stock recoil rod without requiring any modification.

The third spring which is contained within the recoil rod controls the movement of the slide so it never rams on the frame.

How it works:




This kit includes 4 different in length and strengh external springs , for the 2 gray coated springs their wire diameter is 1.0mm and are lighter during the slide travel than the 2 silver coated springs with wire diameter 1.05mm.
