[5] Many of the MDR rifle components are produced using modern Metal injection molding (MIM) metalworking processes that are becoming more common in the firearm industry.

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.

[13] In addition to addressing the criticism, Desert Tech provided a technical root cause analysis presentation on the platform failures and resulting improvements with the generation 2 gas system.

As a supplemental incentive, Desert Tech announced their MDR generation 2 gas system upgrade was to be covered under their warranty program for all owners.

[15] The firearm was offered in .300 BLK, 6.5 Creedmoor (The first production semi-auto bullpup chambered in this cartridge), along with its original .223/5.56 and .308/7.62 calibers[1][5] as well as 20" barrel and side ejection options.

[10] Desert Tech halted production of the .300 BLK Rifle and conversion kits in late 2020 up until January of 2023.

[17] A large multi shooter community study in 2022, including aftermarket precision vendors such as ES Tactical, was able to quantify the performance of the stock OEM barrel between 1.9 and 5.6 MOA with 5 shot groups in .308 with various ammunition as well as identified a contributing failure mode of Trunnion fasteners loosening over time.

In addition, Desert Tech presented their research data that clearly showed suppressors significantly improve the accuracy of Rifles by upwards of 1 MOA for the MDR.

In addition a heavy hammer spring is available for special order to resolve light strike failures on hardened primers.

[25] On March 18, 2021, a collaboration between Desert Tech and BLK LBL Bipods was announced to develop, produce, and sell the Mantis handguard.

[26] In March 2022, ES Tactical, a Desert Tech Dealer who specializes in precision upgrade parts,[27] began to sell after market caliber conversion kits in .350 Legend and .450 Bushmaster, resulting in the first bullpup to be chambered in those cartridges.

All future MDRx Rifles and Barrel Assemblies would no longer include a Pic rail mounted gas block and be lighter.

In addition, the company distributed an email notice to its customers, on August 18, indicating that a registered gunsmith could remove the pic rail from any existing barrel assembly without voiding the factory lifetime warranty.

[9] On April 17th, 2024, Desert tech announced an MDRx upgrade kit for the out of production Rifle to incorporate lessons learned from the WLVRN design to improve performance.

[35] The NGSAR rifle included improvements in the design such as a T-Worx battery powered integrated data rail, onboard round counter, longer receiver, bolt carrier, barrel extension, charging handle, forward eject system, barrel mounting system, proprietary 6.8mm PCP magazines, custom flow reflex suppressor, CNOD day/night optic.

The rifle included adding JB weld between the MDRx trunnion and chassis to reduce trunnion movement under recoil of full power cartridges, a modified SRS barrel, a modified Gas Block, and a full length aluminum front handguard.
