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, and improved gas block drainage to ensure maximum reliable performance in water and mud submersion testing. The trigger pull and creep have been reduced to allow for more accurate shooting capability. The compliant rifle qualifies as a featureless rifle with 20" barrel, Desert Tech's Ratchet compensator, a 10 round magazine, and a shark fin that is attached to the grip of the rifle.
