Hey Lee,
It may look a little more like a pistol than a full-size blaster, but as much as we all want to look like Boba did in the movies, sometimes you've gotta make due with what you've got. It's a great toy for what it is. Speaking of the movies, the Hasbro is based on the blaster as seen in ROTJ, so if you're going for ESB, than the barrel is completely different.
Cheers!
Mark
