T86 assault rifle
The T86 (聯勤 Type 86) rifle is a gas-operated, magazine-fed, assault rifle. It is the second original rifle design conducted by the 205th Armory of Combined Logistics Command of the Republic of China Armed Forces. Though it saw limited production and service after a protracted development process, it became the basis of the T91 currently in volume production for the Taiwanese armed forces.
Development of the T86 started in 1992, with the stated objective of replacing the T65 series. Several radical concepts, such as caseless ammunition, were explored but ultimately rejected due to high risk. Still, the XT86 prototype revealed to the public in 1996 demonstrated several innovative features and significant departure from US influence in firearms design.
However, the ROC military was more confident in the tried-and-true T65 design, and instructed the 205th Armory to redesign the rifle. The XT86 pre-production model rolled out in 1997 showed a return to the T65's features, especially the T65K3 carbine.
The T86 design was finalized in 1998, and officially named the 5.56 mm T86 Combat Rifle (5.56公厘T86戰鬥步槍).
The finalized T86 design is an evolution of the T65 series. It inherits the short-stroke gas piston operated system from the T65 as well as the rotating bolt design. Upper and lower receiver are made with aircraft-grade aluminum. The side-folding metal stock on the prototype was replaced with an M4 carbine style polymer telescopic stock and buffer mechanism. The polymer handguard from the prototype was retained.
The controls of the T86 are similar to the T65 and M16. The T86 has a 4-position selector with safe, semiautomatic, three-round burst, and automatic settings. Like the T65K2, the T86 utilizes an M16A2-style front post/rear peephole sight. The rear sight is adjustable for windage and elevation. One notable difference is that the T86 does not have a forward assist, and the brass deflector is shaped differently.
The T86 has a 375 mm (14.8 in) barrel with flash suppressor. The rate of rifling twist is one twist in 178 mm (7.0 in). The bore is chrome-lined and the T86 can fire all 5.56×45mm NATO standard ammunition. Magazines used by the ROC military feature two protrusions on each side to avoid over-insertion, but standard STANAG magazines are compatible.
The T86 is modular and can be field-stripped without using special tools. The gas piston system and the trigger assembly can be removed as complete assemblies for maintenance, reducing the risk of losing small parts.
