All are alloy. Sig only uses polymer on some of their pistol frames (2022/2009/2032/P250).
Pretty sure all the AR polymer lowers are crap, but I'm not an AR guy, so I really couldn't tell you.
Good luck with the 556. Love the hell out of mine.

Yep Sig 556 lowers should be aluminum.

Metal, Paul. My bud at work is currently in the middle of a SIG fit. Have to say, it's good kit. They know how to bang a rifel together.
