Odin Innovations M12 Sidewinder Speed Loader (Color: Black)

"Easy to use, great design, portable, and highly recommended.

"It would constantly only load between 90 and 100 BB in a 120 round magazine

"This is decent but broke pretty quickly and stopped working. That's happened with a ton of these manual speed loaders so I recommend getting the Autobot speedloader. It's only 90 bucks (which is less than I've spent on manual speed loaders overall) and works incredibly.
