That ETS universal rifle speed loader is great. Makes it so I don't have to bring multiple maglula loaders to the range when I take the AUG and the AR. It also grabs rounds out of organized shell holder boxes better than the maglula. The only issue I have with it is you kinda have to hold it on the AUG mags, where the AUG maglula loader fits nice and snug. But the Maglula is more for loading off of stripper clips. ETS's 9mm/40 loader works great with the A1 and A2 pistol mags also (don't know about the earlier models).
