Small metal stocks, a top folding stock, and the usage of brittle, slowly reloading helical magazines are just a few of the poorly built components on the Type 88-2 assault rifle from North Korea.
The North Korean military uses the Type 88-2 assault rifle, which is based on a clone of the AK-74 series. However, the rifle has some unusual design features. The stock is extremely small and made of metal, making it uncomfortable to use in the North Korean winter. The Type 88-2 also has a top folding stock, which sacrifices support and aiming ability. The North Korean military switched to using helical magazines with the Type 88-2, which are slow to reload and fragile in design. Some speculate that the rifle was purposely designed poorly by mutinous engineers.
