The new official Clone Wars timeline has not yet been established by Lucasfilm. The exact chronology of the events described in this article is currently unknown.
The EE-3 carbine rifle was a blaster that was modeled after the E-11 blaster rifle used by ImperialStormtroopers or possibly vice vesa. The rifle consisted of a small handle attached to a long circular barrel. An alternate version of this model features a modified scope mounting and hand grips that run along the length of the barrel.
The bounty hunterBoba Fett almost exclusively used the EE-3 as his primary weapon. Fett modified his by adding a stock and an electronic scope for distance shooting, making it a dangerous weapon. Prince Xizor also used an EE-3 to try to kill Luke Skywalker as the Jedi and his friends escaped the Falleen's palace on Coruscant. Another user of this weapon was the Zabrakbounty hunterSugi, who wielded it during the Clone Wars. Kiera Swan also used this weapon in the Box. The EE-3 is also the standard issue weapon for the Mandalorian Protectors.
Sugi's use of a EE-3 in The Clone Wars television series caused a continuity error
In Star Wars: Battlefront II, the rifle discharges a three-round burst. Note also that in the game, Fett's blaster uses the same graphics as the E-11 Blaster Rifle. It is likely, however, that this was simply done to save memory space on the disk, as many similar situations take place with Jango Fett, Leia Organa, and other characters.
The prop Boba Fett uses in the films is a modified Webley & Scott № 1 Mark "I" Flare Gun, built for use by British troops during WWI. To make it into the weapon of an intergalactic bounty hunter, prop makers added a rifle scope, some detail parts to the stock and either an MPP Microflash or Heiland Synchronar flash unit (the same models used for Darth Vader’s Lightsaber) protruding from the end of the barrel. There were also some blocky detail pieces added between the scope mounts and the body of the gun.
In Star Wars Episode VI: Return of the Jedi, the Webley & Scott was used again, only this time more detail was added, primarily to the barrel. Presumably this was because the prop would be featured prominently in the skiff battle scenes where Luke Skywalker slices it in half with his lightsaber. The Heiland flash unit was gone and a beefier barrel with ribbed hand grips was built over the existing flare gun barrel. The same scope was used, but for some reason it was mounted pointing in the opposite direction from the Star Wars Episode V: The Empire Strikes Back version. The scope was also mounted farther back on the gun and slightly lower. The blocky detail parts on the scope mounts were also eliminated.
In 2010, "Bounty Hunters," an episode of the Star Wars: The Clone Wars television series, showed a bounty hunter wielding an EE-3. Because the series takes place before 19 BBY, and the EE-3 was established to be modeled after the E-11, an Imperial stormtroopers' weapon that was first manufactured around the time of the Galactic Civil War, the weapon's portrayal in the show creates a continuity error. Likewise, the EE-3 later reappeared in the show in the episode "The Box" and again in "Eminence." To date, the inconsistency remains.
