Re: aluminum base?

Not true. As an analogy, many auto manufacturers use steel blocks and aluminum heads where maximum heat expansion and cool down is present, a rifle will (generally) not reach even close those temps. You will be fine using a aluminum base with steel rings, the scope is aluminum as well.
