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 Raiden Flash Hider installed! The Raiden Flash Hider has been designed specifically for 5.56/.223 to maximize performance for your MDRX and any other brand rifle. The Raiden allows for faster target acquisition on follow up shots and improved accuracy because it eliminates barrel rise using caliber specific porting. Their unique interlaced 3 prong design minimizes concussion while hiding flash signature. MDRX Conversion Kits are available in multiple calibers, barrel lengths and in forward or side eject configurations.
