T65 assault rifle was developed at Taiwan state arsenal to replace obsolete 7,62mm M14 rifles of US origin. The T65 rifle closely resembles US-made M16A1 rifle and is probably made on US-supplied machinery, although the Taiwanese rifle has some differences in design and appearance. Reports on original T65 rifle suggested that it performed not satisfactory, so it was improved and became T65K2 (also sometimes referred to as T68). Later on, a T86 carbine was developed - it is very similar externally to US-made M4 carbine although it has piston-type gas action of T65. The last weapon in this line-up is T91 carbine, which can be described as T86 with carrying handle replaced by Picatinny-type accessory rail.
T65 assault rifle is gas operated, selective fired weapon. It uses M16-type two-part aluminum receiver and similar rotating bolt action, although gas system is different - it has short-stroke gas piston, located above the barrel and concealed within handguards. The T65 rifles replaced carrying handle of M16 pattern with rear sight block; otherwise it was similar to M16A1. Starting from T65K2 Taiwanese designers returned the carrying handle (removable on T91 carbine). T65 uses magazines compatible with M16 rifles.
