DPM "ADJUSTABLE" System for Gen 4 Glock models: 20-21-41SF

DPM MRS for Glock 20-21-41SF Gen 4 - 6 Adjustable User Settings - Stainless Steel (Black Oxide) Washers

The Advanced Adjustable Recoil Reduction System offers 6 Adjustalbe User settings. The included 2 Different Buffer Washers and the 3 Different External Springs can serve Factory and Heavy Ammo.

• National Tactical Officers Association Tested & Recommended.

This 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 external springs are different in length with the longer offering heavier slide travel and locking than the shorter spring.

**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.**
