Last year, we posted an image of the JGSDF Howa Type 89 Rifle. In that post, we had mentioned a mythical modernized version that appeared to be an Airsoft version made by Tokyo Marui. Well these pictures do not appear to be airsoft.
Below is a photo of a typical Howa Type 89 Rifle.
You can see a modified Type 89 rifle below. It is using a Remington ACR stock and has a rail system on the handguard.
Take a look at the soldier on the left. He has what appears to be a Land Warrior like HUD system on his helmet.
In the photo posted at the top, you can see the JGSDF soldiers have what I assume to be fold out screens for their OICW like optic system.
Below are some images my friend Kris K from Korea found. However neither of us read Japanese. He said the image uploader credits these to Howa Industries. At first glance it looks like an FNH SCAR.
