In the "it's time for a new service rifle" department, Taiwan is joining that club:
"The entirely domestically developed and built rifle features numerous improvements over the existing T91 and T65K2 models, said Lieutenant Lee Chien-ting (???), who is involved in the research and development of the rifle at the bureau.
The barrel of the XT112 rifle is polygonal and thickened compared with the T91 and T65K2 models, resulting in the XT112's improved accuracy of groups of 9.8 cm at 100 m compared to the T91's groups of 14.5 cm at 100 m, Lee said.
The barrel also boasts a longer life expectancy of 10,000 rounds, compared with 6,000 rounds with previous models.
In addition, the selector lever, the magazine release button, and cocking handle latch, are present on both sides of the XT112 to allow easy access regardless of the user's dominant hand, whereas on the previous models they are only present on one side, he said."
The mag in the pictured rifle appears to be the same (Taiwan-made) mag sold here under the UTG Leapers brand, but in a FDE color:
