I just want it to use while hunting. It doesn't need to have anything for high heat since it will just be for hunting and at the range I won't have it on. My silencer is a polished silver and it's super shinny.
This is actually the opposite use case for covers for most people. For hunting, I would just high temp spray paint it to knock the glare off. Covers are mainly used to reduce mirage after multiple shots. You would just be adding unnecessary weight in most hunting scenarios.
