Airsoft vs Everything shows an ACM (All China Made) Dragunov airsoft rifle with ACM PSO in this video... "I bought this Dragunov and PSO scope from the same brand (A.C.M.) but they were not too compatible with each other. I cant decide, Dragunov's rail is bigger/wider or PSO claws were smaller, but...deflection was 2-3mm!! Thats a lot!

I had to make this small modification on them because after I grinded down a bit the claws, Dragunov's rail can't hold it properly."
