The MDRX (Micro Dynamic Rifle Xtreme) is designed for maximum concealment and ambidexterity, allowing operators to return fire at any angle without exposing unnecessary parts of their body to threats. It features upgraded polymer resin to better withstand high impact falls; gas block drainage to ensure maximum reliable performance in water and mud submersion testing; trigger pull and creep have been reduced to allow for more accurate shooting capability; flash suppressor is designed to reduce the flash better than current options found on the M4. Desert Tech's patented forward-ejection system allows operators to quickly transition between shoulders without any need to reconfigure the rifle.
