Welcome aboard!
We were all new to this at some point. You're fortunate to have found a site like ours to start with. We've got a great group of folks here on Mossberg Owners and the atmosphere is very laid back. There are no stupid questions, so please feel free to ask away. If there is something you don't feel comfortable asking in an open forum, please utilize your PMs to contact us off the radar. 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 if you have any questions while you're getting used to the site.
Enjoy!
