Happy to find that this was steel instead of aluminum. The black oxide coating is well applied and the price is right.

Made from steel by TinCuda, Verified Owner, February 26, 2025
I got the black version of this button. Most of these are made from plastic or aluminum. The one that I received was made from steel. It had a nice black finish, was cut mil-spec. This was just what I was looking for.

smooth action by Kintrp, Verified Owner, November 12, 2023
Added to my BCM bolt and it’s defiantly smoother, installation was very easy, there is a kit but it requires removal of the gas key. This is much easier with the same result. Cost is less as well, the coating seems like it will last.
