A video demo of the Elite Force 140-round Midcap Magazine for M4 and M16 AEGs was just posted by Evike.com. Available in packs of 10, these are priced at US$63.00. The feeding looks good as shown in the video as the presenter was able to use the 10-pack with no feeding issues at all. These midcaps are compatible with Elite Force and Tokyo Marui-compatible M4 and M16 AEGs.
