Technical Specifications
The DPM Recoil Rod for the FN 509 Compact & Midsize Tactical models is a direct replacement for the stock recoil rod and does not change the configuration of the pistol.
This high-end tech system works due to the multi-spring intricate rod (2 springs) in combination with the 4 external springs that work as buffers and control the functionality of the pistol.
The system includes 4 external springs, 2 x 1.0mm wire diameter and 2 x 1.15mm wire diameter, all with different power rates. The soft springs are designed to serve threaded barrels and compensator modifications.
