confused
It took asking Mossberg directly which heat shield fits my 590a1.
I ordered the one they said from Brownells. Not until I received it was I informed that it did NOT include the needed bolts and spacer that do NOT come with it? The spacer I bought was marked as fitting a model 500 and nowhere does it say it ALSO fits the 590a1. It took me a lot of time to figure out which parts.
