Welcome to Mossberg Owners Forum! I was the one messaging you over on Twitter. Congratulations on your new Mossberg 590A1. Feel free to post up any and all questions that you may have!
You certainly have great taste in shotguns! We've got a great group of folks here on Mossberg Owners and the atmosphere is very laid back. The only thing we like better than discussing each other's guns is lookin at 'em, so be sure to post up some pics of any firearms you own the various sub-forums. Let us know when you're ready with your questions.
