Barrel Length: 20"
Ejection Configuration: Side Eject
Magazine Capacity: 30 round
Compatibility: MDRX Rifles
The Multi-Caliber modularity of the MDRX is what sets it years ahead of the competition. Caliber conversions can be done with minimal tools and in less than a few minutes. The Desert Tech MDRX Conversion Kit comes with everything you need to switch your MDR or MDRX rifle from one caliber to another. This MDRX Conversion kit comes with Desert Tech’s proprietary Ratchet Compensator installed! The Ratchet Compensator has been designed specifically for each caliber to maximize performance for your MDRX and any other brand rifle. The Ratchet Compensator reduces recoil while giving better muzzle control and nearly eliminating all barrel rise. MDRX Conversion Kits are available in multiple calibers, barrel lengths and in forward or side eject configurations. If you plan on changing your rifle from Forward Eject to Side Eject, or Side Eject to Forward Eject, additional "FE to SE" or "SE to FE" conversion kits will be required.
MDRX Conversion Kits give you the ability to have multiple rifles/calibers out of one platform, allowing changing from one caliber to the another without having to re-familiarize yourself with a completely different cheek weld, grip, trigger, controls, optic or balance.
Included in this package:
• MDRX 20" Side Eject Barrel Assembly - ready to install
• Desert Tech's Raiden Flash Hider (installed)

* This kit will convert your current Side Eject MDRX from one caliber to another. If you are converting your MDRX from a Forward Eject configuration, you will also need to purchase the FE to SE kit which will convert your MDRX rifle from the Forward Eject configuration to the Side Eject configuration. If you have an original MDR and want to convert it to the Side Eject configuration, in addition to the kits listed above, you will also need to purchase the updated MDRX Bolt Carrier which is modified to accept the Side Eject Chute Cover.
