Country of origin: Taiwan

Notes

The T65 project began in 1968 as an effort to modernize Taiwan's infantry weapons from the 7.62mm M14 to a 5.56mm platform. While the rifle closely resembles the M16A1 externally with its carrying handle, front sight post, and pistol grip, the internal gas system is significantly different, using a short-stroke gas piston similar to the AR-18 rather than the M16's direct impingement system. The T65K1 variant introduced minor improvements, while the T65K2 added a three-round burst capability and additional refinements. Later production models featured a four-position fire selector (safe, semi, burst, and full auto). The rifle accepts standard STANAG magazines and maintains parts commonality with M16 components where possible. The T65 was eventually superseded by the T91 (essentially an improved T65K2 with a shorter barrel and rail system) starting in 2003.

Background

The T65 represented Taiwan's determination to achieve small arms self-sufficiency during a period of diplomatic isolation. When the United States established formal diplomatic relations with the People's Republic of China in 1979, Taiwan's ability to produce its own infantry weapons became strategically vital. The T65's clever combination of M16 ergonomics with a more reliable gas piston system reflected pragmatic Taiwanese engineering -- improving on the American design while maintaining familiar operation for troops trained on M16 variants.
