MDP-9 GEN2 Roller Delayed Upper
The MDP-9 roller delayed action is now available as a stand alone upper receiver assembly. This is a direct upgrade for existing Angstadt Arms UDP-9 firearms and 3rd party AR9 lower receivers.
Experience unmatched portability without compromising performance
- Light and Agile: With a length of just 14” and weighing 3.7lbs, the MDP-9 promises easy concealment
- Smooth Performance: Leveraging the roller delayed system, expect significantly less recoil, ensuring precision even in high-pressure scenarios

In a world filled with unforeseen threats, traditional firearms lack the combination of power and compactness needed for immediate response.
The MDP-9 is designed to be light, small, yet fully functional, offering a revolutionary roller delay action that reduces recoil. Gain the peace of mind and confidence you need for protection in any situation, with the perfect balance of size and strength.

Lower Receiver Compatibility:
The MDP-9 upper is designed to work with a wide range of AR9 GLOCK magazine lower receivers, as well as mil-spec AR-15 receivers.
For the best possible function we strongly recommend our AR9 lower receiver however, we have successfully tested the MDP-9 upper with these 3rd party receivers. Please note due to 3rd party manufacturing tolerances we can’t ensure 100% reliability in every third party configuration.
