By the image i thought i was getting a steel block - ODIN Works Low Profile Gas Block

I don't know where I messed up the order but the image I saw and am looking at now is a Steel block. What I received was a Aluminum block. I am one who was lucky enough to have an Aluminum block fail.. It was not pretty. When hot gasses burned my hand at that time I vowed never to use Aluminum again. I am in the process of an RMA.
