Since I was so happy with the MagLula, I had to try out the Lula. Rifle magazines are generally easier than pistol magazines to deal with, but the Lula makes then even easier. The way it works is you place the Lula on top of the mag with big opening towards the business end of the bullets. The lula will snap onto the mag catch for a solid connection. Now when moving the lever back and forth this will cycle between pushing bullets down on the right and left side of the mag. When pushed down this allows space for a round to be inserted. So when reloading: one angles the mag back for gravity assistance, puts in a round, cycles the lever, and repeats till full.
This isn't super fast, but is noticably faster than by hand and will keep the wear off your hands while protecting your feed lips on your mag. For unloading the Lula really shines. It may take a little fidgiting to figure out which way the lever needs to be to get started, but once going the bullets fall out as fast and one can move the lever. Just point the mag top down and go at it. The lever can be pushed down into the body for smaller stowage size and a keyring is standard on the back for an attachment point. The M16 / AR 15 version works on many NATO variants such as you can see on my pics, it fits great on Magpul PMags. Do note this model does not work on HK high reliability mags or SA-80 magazines, but a version is in development. For other weapons many Lula versions are availble as well such as for AKs, MP5s, Uzis, M14s, and more. Well worth the price, check out the site links for more intel.
