Desert Tech MDR
The Desert Tech MDR (Micro Dynamic Rifle) is a family of bullpup semi-automatic rifles designed by Desert Tech (formerly Desert Tactical Arms) in 2014. A second generation of the MDR was later developed, designated as the MDRx (Micro Dynamic Rifle eXtreme). A third generation was announced, serving as a successor to the MDRx series, designated as the Desert Tech WLVRN.
The MDR's first public debut was in 2014 at Shot Show and was discontinued on January 18, 2024, right before Shot Show 2024.
The Desert Tech MDR is a gas operated, conventional rotary bolt bullpup rifle. The gas system features a gas piston located above the barrel and a 6 position manual gas regulator.
The MDR is designed to be ambidextrous. The MDR contains an ambidextrous forward and side eject port and viewing window that allows for tool free forward ejector side change. A non reciprocating ambidextrous charging handle is installed on both sides of the gun, and two or three-position safety / selector levers and magazine release are provided on both sides of the pistol grip. The rifle is compatible with Desert Tech caliber conversion kits that allow the rifle to change caliber. This provides a unique feature in which the rifle chassis can accept both intermediate cartridges and full-powered rifle cartridges on the same serial number platform (such as 5.56×45mm NATO and 7.62×51mm NATO magazines). The Colt CM901 is one of the early designs able to accept different cartridge categories on the same platform with a caliber conversion kit.
The outer shell of the gun is made from impact-resistant polymer with an aluminium receiver.
Many of the MDR’s components are produced using modern Metal injection molding (MIM) metalworking processes that are becoming more common in the firearm industry. MDR MIM parts including the Barrel Block (Trunnion), Gas Block, Bolt Catch, 7.62 mag conversion bar, ejector retainer, and extractor link, are produced by Indo-MIM Pvt. Ltd., India. Indo-MIM Pvt, Ltd received the 2017 distinction in hand/tools award by PIM international for their innovation in MIM development and part cost reduction.
The .308/7.62 MDR was 10,000 round endurance tested with .308 win 150 grain FMJ American Eagle, 7.62x51 149 grain American Eagle, 7.62 m80 ball US Surplus and averaged 1 failure in 2000 rounds.
The 2017 MDR in .308/7.62 win received public feedback that resulted in an upgrade program by Desert Tech on the gas and extractor system in 2019 to improve the rifle's ammunition tolerance without having to adjust the gas setting as frequently. This update is considered the Generation 2 MDR Gas System.
