Optimus Prime Battle Rig Blaster

The Optimus Prime Battle Rig Blaster is a Hasbro blaster that was released in 2007 to promote the film Transformers.

It comes packaged with three Screamin' Mega Darts.

Details
It can transform from truck to blaster. Much like the Cyber Stryke Gear Strongarm, this blaster is designed to be worn on the user's arm. When in blaster form, there are sights that are also the windows for the rig. It is designed for right handed use only and is not designed for ambidextrous use.

Reloading and firing
To reload the Optimus Prime Battle Rig Blaster, simply insert one dart into the muzzle of the blaster. Pull the priming handle back until it cannot go back any further in order to prime the blaster. Make sure the blaster is in its transformed position before attempting to prime the blaster.

Pull the trigger to fire the blaster.

Trivia

 * The multilingual European packaging identifies the blaster as the Optimus Prime Big Rig Blaster.
