If you think the Uplula is cool, try the Maglula for loading AR mags. Row the paddle and drop in cartridges, genius.
The Uplula loads all calibers .380 and above, single or double stack.
They've also brought out the BabyLula for .22 to ,380. They seem to be hard to find (low priced).
My Lula fills my .380 mags, but they are so small the lula swallows them up.
For those of you who haven't tried one, the slowest part of loading magazines is picking the cartridges out of the box. Really. I fumble everything, and it's easy for me.
Invented by some Israeli Rocket scientist, thus the odd name.
