The Desert Tech MDRX Chassis, 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.

Built on a gas piston system and featuring a compact bullpup design, the MDRX flawlessly combines functionality, modularity, and ergonomics. The MDRX continues to utilize the MDR’s patented forward ejection system that makes the rifle ambidextrous without reconfiguration, as well as sending spent brass toward the target and not the guy next to you. The rifle features a full length Picatinny rail that extends to the end of the handguard as well as industry standard M-Lok attachment points. The MDRX, is available in four chamberings: .223 Wylde, .300 BLACKOUT, .308 Winchester and 6.5 Creedmoor.
