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. All .300 BLK, .308win and 6.5CM MDRX Conversion kits come 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.
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.

* This kit will convert your current Forward Eject MDR or MDRX from one caliber to another. If you are converting your MDRX from a side eject configuration, you will also need to purchase the SE to FE kit which will convert your rifle from the side eject configuration to the forward eject configuration.
* Note the .300 BLK conversion kit uses a unique bolt assembly and recoil spring that is not compatible with any other MDRX conversion kit. If you are converting your rifle from any other caliber, you will need a complete .300 BLK conversion kit.
