The RGM-79K9 GM Sniper K9 is a custom mobile suit from the Gundam Build Fighters anime series. Based on the RGM-79SP GM Sniper II, the Gunpla is built by Julio Renato and Mario Renato and primarily piloted by Julio.

Based on the RGM-79SP GM Sniper II from the Mobile Suit Gundam 0080: War in the Pocket, the GM Sniper K9 has additional armor and is normally armed with two beam sabers, two different beam sniper rifles, two beam guns and a heat knife. It can also be equipped with an additional shield and machine gun. Despite the name, the GM Sniper K9, like its predecessor, is not just limited to carrying out sniper attacks, it can also be easily used in other forms of combat. A special feature of the suit is that its backpack can detach and transform into the K9 Dog Pack, a four-legged support unit that can mount a sniper rifle as its head and act as a long range self-propelled artillery. The K9 Dog Pack also carries an APC for covert operations. The suit is also equipped with the EXAM System.
