T91 Assault Rifle

The T91 represents the culmination of Taiwan's decades-long effort to develop an indigenous service rifle, tracing its lineage from the T65 (1976), through the T86 (2000), to the T91 (2003). Taiwan's arms industry, isolated diplomatically from most of the world, developed the T91 as a modern combat rifle that could compete on the international market despite the country's unique political situation. The rifle's successful export to multiple Middle Eastern and Southeast Asian nations demonstrated that Taiwan's defense industry could produce world-class small arms.

In 2003, the Taiwanese Army ordered 101,162 T91 rifles as force-wide replacements for all service rifles, with delivery scheduled from 2004 to 2008. By 2008, the T91 had replaced all previous service rifles including the T65 series across all branches of the Taiwanese military. The T91K3 variant features polygonal rifling for increased barrel life and improved accuracy. The telescoping stock was designed based on Taiwanese military and police experience with the M4 Carbine, resulting in improved recoil transfer and handling. Production numbers exceed 240,000 for Taiwan alone, with significant export orders to Jordan (20,000), Kuwait (18,000), the UAE (10,000), and Bosnia and Herzegovina (5,000).
