I put together a KYL made from 1" gongs turned on edge from https://shootingtargets7.com/steel-targets.html I used 3/16",1/4", 3/8", 1/2", and 5/8". for 50 yds shooting, that is all I needed ( Have a full KYL. You could stack then together to get up to a full 2". I have less than $30 in the gongs, I had the other stuff.
