Frequently Asked Questions

What makes the AN-94's firing mechanism unique?

The AN-94's unique firing mechanism relies on its internal receiver unit sliding within the outer housing. This movement, controlled by a special barrel return spring and recoil action, interacts with the sear to enable its distinct firing modes, including a high-speed two-round burst.

How does the AN-94's barrel return spring work?

The AN-94 features a unique barrel return spring within the receiver. It uses an oval wire hook that connects to a lug on the barrel, actively pulling the internal receiver unit forward after recoil, which is crucial for its cycling and firing timing.

What are the firing rates for the AN-94?

The AN-94 has distinct firing rates for its modes. Its two-round burst mode operates at an exceptionally high 1800 RPM, while its traditional full-automatic mode fires at a rate of 600 RPM. Semi-automatic is also available.

What key components are identified in the AN-94 teardown?

During the teardown, key components like the muzzle device, barrel, gas port, gas cylinder, gas piston, bolt assembly, the internal receiver unit, and the specialized barrel return spring are identified and explained.
