Fortress conducts a test on their prototype VFC KS-1 CO2 Custom SPEC2 airsoft rifle under extreme conditions. What began as a plan to fire 60 magazines was ultimately extended, with the hosts successfully shooting an ambitious 100 magazines consecutively to truly push the limits of the CO2-powered gas blowback rifle.

During the extended, high-stress full-auto test, the rifle performed exceptionally well, showing its reliable function without a single instance of a feeding issue or jam. The only mechanical problem encountered was the loosening and eventual loss of the small screws securing the ambidextrous safety/selector lever. They determined this minor issue could be easily fixed by applying a thread-locking compound, ensuring it did not affect the weapon's core shooting functionality.

The post-test inspection confirmed the custom rifle's robust build quality. A thorough examination of the receiver, bolt carrier, and internal components revealed no significant damage, such as frame cracks or major wear, despite the continuous heavy use. They concluded that the VFC KS-1 CO2 Custom SPEC2 is remarkably sturdy and highly reliable.
