The Brain Exploder got a brand new adapter for the Odin Innovations M12 Sidewinder allowing you to use it with other types of midcap magazines... "The Odin Innovations M12 Sidewinder  is one of the best inventions for the airsoft world, not having to break your thumbs to load midcap magazines is a welcome change however they do have one limitation they are magazine specific and thus far only compatible with M4 magazines. Well this is an accessory that allows you to use your Odin Innovations M12 Sidewinder for other types of midcap magazines.

By simply clicking this BrainExploder Creations adapter in place of a M4 magazine the adapter will spit out BBs though the open end when cranked. This end can then be placed atop any midcap magazines and used to fill those magazines.

For best results rest the magazine against something firm as you push the Odin Innovations M12 Sidewinder on top of it and crank the handle. I find it best to seat the midcap on or in your gear so you don't have to hold it and then load it up."
