The Pindad SS Bullpup (Senapan Serbu, lit. "assault rifle"), also known as the Pindad SS3, was a prototype Indonesian bullpup assault rifle designed in 2010 by PT Pindad and produced in prototype form only.
The SS Bullpup was an adaptation of the Pindad SS1 rifle in a bullpup format, as a modern rifle for the Indonesian military. The weapon was showcased at IndoDefence 2010 but has not entered production. The weapon appears to have been canceled in favor of the Pindad SS3 battle rifle.
