The M5 XDC Upper replaces the entire upper receiver on your M5 for an entirely new look.
MONOLITHIC RAIL - Starting from the top down, the M5 XDC Upper receiver sits 1/2" higher than a standard M5 rail, for a built-in riser effect. A monolithic 14" rail gives you plenty of room to mount all of your necessary accessories.
MLOK Compatibility - opens up access to thousands of handguard mounted accessories like rails, covers, mounts, grips, and more. See our Handguard Accessories section for more options.
BOLT RESET HANDLE - The M5 XDC Upper receiver adds a new forward ambidextrous Bolt Reset Handle to your M5 that can be used in the case of jams or misfeeds.
