The Desert Tech MDRX takes the company's revolutionary bullpup rifle design to the next level. MDRX rifles now feature an upgraded polymer resin formula for enhanced durability against high impact falls. Additionally, gas block drainage on the MDRX has been improved to dramatically increase reliability after submersion in mud and water. The trigger of the MDRX has been improved, providing a lighter pull with less creep. All MDRX rifles now feature the new Ratchet Compensator, which provides excellent control and recoil reduction without subjecting the shooter to gas blowback.
