Acronym vomit seems useless, but as inelegant as it is it's actually quite useful.
The Fabrique Nationale (America) Improved Performance Carbine is the weapon component of the Individual Weapon System, which consists of the .264 LICC cartridge, IPC itself, 25-round magazines for the IPC, and a QD suppressor.
The LICC (Lightweight Intermediate Caliber Cartridge) program also includes another weapon system, the LICC-AMG.
FN adapted the .264 USA cartridge and developed both weapons for the Irregular Warfare Technical Support Directorate, but now they seem to be marketing them together with the MTL-30, which follows the same design language.
