We?ve got three ways to load MSR magazines ? and none involve your thumbs. The Butler Creek® ASAP? Universal AR15/M16 Magazine Loader fills up mags almost as fast as they can be emptied.
 
Loose ammo can be loaded one round at a time with a simple click or engage the loading arm to expedite the process. The loading arm can handle up to 10 rounds of loose ammo or ammo in a stripper clip and the rounds are locked into the mag with a quick push. Spend more time shooting and less time reloading.
