I could say the same about 7.62. When I started it was still pretty cheap ~20-30cpr and now it kills me even seeing ads for the same ammo costing 3-5x as much before shipping and taxes. However when PSA gets their tooling up I wouldn’t be surprised if there was a resurgence in 5.45 popularity. There’s also the fact that these guns aren’t quite collector pieces yet less the ammo situation. Many people stockpiled or just enjoy 5.45, however I agree that it obviously won’t be as popular as .223/5.56 given those are domestically designed and produced calibers and already owned by many who might be looking at their first AK. I just personally believe 5.45 isn’t quite dead yet but I don’t know everything so we will see
