I’m not 100% sure on how it’s made but I believe it’s full rubber. I contacted Slavefive and he was great about explaining the different grades. There is an increase in price between A & B grades. I went A grade, I’ve seen B grades that are just as good. I haven’t dropped mine but I think it would hold up well. Although some parts that hang off worry me. I did not weather mine used it right out of the box cause I though it looked great as is.
Edit after post...
Now that I think about it. I did drill small holes in the back for the D-ring and it was all rubber.
