The WESTAR-M5 blaster rifle was a blaster rifle used during the Clone Wars by the Grand Army of the Republic. They were mainly used by Advanced Recon Commandos and Galactic Marines during the later years of the conflict. They were very efficient and deadly weapons that could be fitted with a single shot, pump-action micro rocket launcher. The blaster rifle could be calibrated to fire in semi-automatic, automatic, and burst-fire modes, and could be equipped with a variety of attachments, including a Merr-Sonn PLX-1m micro-rocket launcher that could be used against armored enemies.
