Survival On Purpose visits the DesertTech booth at the SHOT Show 2019 to find our more about the MDR bullpup rifle. An airsoft version is in the works at Silverback Airsoft... "The Desert MDR (Micro Dynamic Rifle) is a fully ambidextrous bullpup style rifle that you can quickly convert to multiple calibers with no special tools. The patented forward ejection keeps the empty brass out of your face."
