The heavy repeating blaster was a large and powerful variant of a blaster rifle.
The heavy repeating blasters were mainly used in bunker emplacements or mounted on combat vehicles, though it could also be wielded by individuals.
The gun could only be used at a rapid fire rate. In its conventional usage, it would often be attached to a power generator to provide an unlimited number of shots, however it could also function with a portable power pack giving it a capacity of 20 shots. The accuracy of the blaster as a personal use weapon was very limited, owing to the difficulty in controlling such a powerful autofire gun. When mounted on a tripod, the weapon became slightly easier to operate.
Heavy repeating blasters were used by the specially trained Clone troopers called ARC Troopers of the Grand Army of the Republic. They were also used by the heavy weapon specialists of the Rebel Alliance Special Forces during the Rebellion era. The Millennium Falcon had a heavy repeating blaster installed on the ventral side as a surface defense cannon. The Galactic Empire's E522 assassin droid sported a heavy repeating blaster among its arsenal.
