Hyperdouraku reviews a DIY Non-Working JGSDF Type 20 Rifle Model Gun with parts that are 3D Printed and can be a good basis on developing an airsoft version... "A review of the new rifle adopted by the Self-Defense Forces, the full scratch of the Type 20 rifle, and the dummy cart model gun. At the Japan Force Meeting JFM held on July 15, 2023, there was a participant who brought a full-scratch Type 20 rifle, so I took a detailed picture.

It should be noted that this model was created by Mr. Kato as a personal hobby and is not for sale."
