Introducing the new M-RAX attachment system by Maxim Defense. Unlike the traditional M-Slot mounting systems, M-RAX utilizes the full slot of your rail, maximizing space. This makes the M-RAX system end-to-end stackable, giving you the option to create seamless monolithic rail sections where needed.

Installation and removal is a breeze. Thanks to the spring-loaded screws, the M-RAX system removes mounting frustrations. Simply push the screw in with a standard hex tool and rotate 90 degrees. The locking lugs engage that easily. No more fighting or timing screws. Just push, turn, and tighten.


  • Easy installation and removal
  • M-RAX sections meet M1913 specifications
  • Patent Pending spring loaded universal interface system eliminates the need to adjust the gap between the T-Nut and accessory to match the thickness of the mounting surface. Simply use the supplied hex key to push the spring loaded hardware through the M-slot, twist 90 degrees to engage, release tension and then tighten normally.
  • Secure mounting point for any picatinny rail-mounted accessories such as grips, lights, lasers, etc.
