A blaster was a ranged weapon that fired bursts of particle beam energy called blaster bolts from a replaceable power cell. Lego® began making Lego versions of them for the Lego® Star Wars theme. Blasters were made from the very beginning, and included in sets as early as 1999. There are at least nine different variations of LEGO blasters.
The original lego blasters were made with a black megaphone-shaped piece with a transparent orange stud on the tip of them. These were from 1999 to 2006, when they changed them to a newer 1-piece version of the gun. This type of gun was also included in one set in 2007, but was discontinued after that.
