Airsoft Atlanta posted on their Facebook two illustrations that show an upcoming Universal Speedloader Adaptor that can be used with the speedloaders such as the Odin M12 Sidewinder... "Coming out soon - the universal speedloader adaptor for midcap airsoft magazines. Compatible with official Odin speedloaders, Maxx, and other Odin style midcap loaders. An innovative adaptor device that mounts into the M4 loader slot allowing use with ALL airsoft midcap magazines. Should work with everything, but we will be fully testing them to ensure total compatibility. Eliminates the need for individual 3D printed adaptors. Stay tuned for more information as they come out in early July."
