A quick demo of the Airsoftjunkiez Custom HPA LCT RPK LCK-16. This model is essentially an AK-12 configured as a light machine gun. This particular build is the shorter barrel version, which they prefer for its compact size, as if they're trying to fit a machine gun into a handbag.

The gun is powered by a Wolverine Airsoft Inferno Gen2 V3 HPA engine and uses .32g BBs. The box magazine isn't automatic, so the user has to manually toggle a switch to feed the BBs. It's like having a high-tech blaster that still requires you to wind up its clockwork heart every now and then. A test fire of the custom RPK-16 followed, showing its performance on targets.
