Além de parecer um ótimo fuzil, destaco a munição dele, criada para perfurar as mais modernas armaduras pessoais militares.

Não vi nada que sugira que este combo arma-munição possa perfurar sequer o nível III NIJ (até o 7,62 x 51 sofre), cupincha:
Importantly, however, a new 5.56x45mm cartridge known as the J-3 high-power cartridge was developed specifically for the Type 20 weapon. The J-3 was designed by the ammunition and precision engineering division of the Japanese company Asahi-Seki. The cartridge weighs 12g (0.4 oz.), is 57.4mm long, is made from steel and red brass, and uses double-base powder. The bullet has a monolithic, high-strength material core. Even though the barrel of the Type 20 is shorter, the combination with the J-3 creates a more powerful bullet designed to penetrate modern body armor.
