Airsoft rifle MDRX, version 2 - black/FDE
The MDR (an acronym for Micro Dynamic Rifle) is a family of autoloading bullpup rifles designed by Desert Tech (formerly Desert Tactical Arms) in 2014. A second generation version of the rifle is marketed as the MDRX (an acronym for Micro Dynamic Rifle eXtreme). In 2018 a military version of the MDR, the NGSAR, was submitted, but was not one of the finalists in the United States Army Next Generation Squad Weapon Program trials to replace standard issue US army Infantry Weapons.
The MDR is designed for future defense needs. Its compact size and superior ergonomocs maximize its portability without sacrificing speed, power, or precision. The MDRX allows mission specific adaptability by changing the rifle's length, sound signature and/or caliber. Its fully ambidextrous design allows seamless shoulder transition.
The Silverback MDR-X is airsoft licensed version of its real steel counterpart manufactured by Desert Tech LLC.
Very realistic in its conception, to mimic the original build and features as much as possible while integrating a high-quality gearbox, able to deliver high performance from DMR to CQB applications.
Update 24.8.2023: These models already include Silverback update package.
