I have a MagLula UpLula and just love it. It really saves your thumbs when trying to load double-stack pistol magazines.
I also have their loaders for the AR-15 and the AK. They will load a mag as fast as you can put the cartridges in it. They also can unload mags just as fast.
Greg Hickok - Hickok45 - just posted a new YouTube video showing how fast and easy it works. Like Greg, I wasn't sent one by MagLula but love it nonetheless. However, if they want to send me one for the FAL, I wouldn't turn it down!
