This is good, since we've come to rely on PDI parts for upgrades nowadays and X-Fire/PDI have come and done the job for us with this. The customised TM Type 89 Japanese SDF rifle with 3-round burst costs around US$560... "This is NOT Tokyo Marui original type 89. We've already installed PDI 05 Inner Barrel, Koutetsu Outer Barrel & Koutetsu Separated muzzle. More realized & heavy weight as real rifle. And you'll get more FPS & better accuracy compared to original by 05 Inner Barrels."
