CPT is a cartridge package from which a user is able to load a 30-round assault rifle magazine in 2-8 seconds. Compared to the traditional magazine loading, which takes 1—2 minutes, this is a remarkable improvement which gives the user operational and tactical edge. CPT is not a magazine loading device or a speed loader. CPT is a cartridge package which is packed with ammunition at the ammunition factory. CPT is very easy to use and can be operated in darkness or in a hot or cold environment, with or without gloves.
