TERA Rilfes had three models. Type 100 and Type 2 were based on Type 99 Rifle and Type 1 was based on Type 44 Cavalry Rifle. Type 1 was not separated but folded. Type 1 was not introduced, because its folding mechanism was not enough reliable. Above is a Type 2 Rifle.
Japan had developed several experimental models of Automatic Rifle, including a copy of US M1 Automatic Rifle (Above). However, non of them were introduced, due to the supply problem of the ammunition.
