I'm not exactly sure if this is the right section for this or not. But I'm currently on the hunt to find some AR550 steel plates or gongs around a 10-12 inches in size. I would also like the thicker 1/2 inch size if that's even possible to find. I just want the plates with two holes in them for mounting to chains. I can find the AR500 all over the place but I'm just wanting something that will last a VERY long time. Much appreciation for any help!
