I was at a Sig Sauer/High Speed Gear media day earlier this year, you can see that article and video by following this link, and during the live fire portion of the event, I noticed that a single RO was able to keep five to six writers with full magazines for the MCX and P320. After the event, I stopped by the ammo tent to see what was what and was introduced to the Magpump. There were models on hand to load 9mm magazines and the AR-15 magazine.
The video truly does a better job explaining the function of the AR magazine Magpump.
So, if you spend a great deal of time at the range training and honing your skills or you are an instructor running live fire classes the Magpump will cut down on your time reloading your magazines and maximize your time with live fire drills. The standard models being made of lightweight high impact polymer, as reviewed here, run about $150 while the Elite loaders made from billet aluminum range from $400 to $800, depending on the model.”
You have a few options depending on your budget and with a no questions asked transferable lifetime warranty you will know your Magpump will stand behind their products. Both the standard and Elite have a ninety round capacity hopper and can load a thirty round magazine in under thirty seconds
