FN 509 LS EDGE 5'' Barrel

DPM Adjustable Mechanical Recoil Reduction System for FN 509 LS EDGE 5'' BARREL

New DPM Recoil Reduction System for the FN 509 LS EDGE 5" Barrel 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 buffer, and controls the functionality of the pistol.

The kit includes 1 Recoil Mechanism and 4 external springs, 2 x 1.1 mm wire diameter and 2 x 1.15mm wire diameter, all with different power rates.

The long springs set is softer than the standard springs.

**As we lead the evolution of recoil reduction technology, products may change versions (new design with different springs, with or without plugs, washers, etc.) without any prior notice.**
