The E-5C, also known as the E-5C heavy blaster rifle, was a model of blaster rifle. The bounty hunter C-21 Highsinger used an E-5C during the Clone Wars. Hondo Ohnaka's pirates also made use of this weapon, particularly Gwarm. The heavy battle droids employed by the Confederacy of Independent Systems were notorious for using these blasters to rain fire upon the clone troopers of the Galactic Republic.
