The Maverick series is Mossberg's "entry level value price" shotgun line. I have owned and operated a Maverick 88 filed model since 1991 without any problems, but then I am not the guy shooting 5,000+ rounds a year.
As hsmith has pointed out, it is not the heavy duty weapon that the 590 Mossys or the Rem 870's are, but for a limited duty low cost shotty, works fine. Better value than that Chinese imported knockoff of the Ithica.
