Actually it is more of VZ 58 (short stroke piston) than AK. (long piston operated)
No it's not. It's a short stroke piston unlike the long stroke for the AK but the actual action is definitely based off the AK not the VZ58. Also the VZ is a tilting block action not rotating bolt. You'll notice the comparison between the Valmet. The Valmet is an AK action. It's the only non prohibited one around.
When my T97 shows up I'll compare it to the Tavor and the Swiss Arms (another AK inspired action).
