Mossberg 500 Field and Slug Shotgun Combo with 28in Barrel, for Hunting, Sporting and Home Defense

The forearm design is defective, and the company will not stand behind it.  About 2 years ago, I bought my son a model 500 shotgun for his birthday to be his own shotgun.  He was 14.  The first time out on opening day, the pins fell out of the handguard and the handguard fell off, and the shotgun was out of action.  So his day was ruined, but things happen.  They sent another identical handguard, but two years later, opening day, the same thing happened.  Keep in mind, this shotgun is pretty much only used for a few days of dove hunting each year.  This is extremely disappointing, so I called their customer service department and they informed me that while there was a more robust system available, they would not supply that.  Even though the shotgun is clearly defective, they would not cover it under warranty.  They put a defective product out on the market, which is evident with a little internet research where others are experiencing the same problem, and won't stand behind it.  That so called warranty is useless because they will not take responsibility for their design flaw.  Thank God this is not a home defense shotgun!

I asked to speak with a supervisor, but the agent refused to escalate.  So this is my only recourse.  I hope someone reads this who will take responsibility and fix this problem, but without a change of course, this will absolutely be the last Mossberg product I buy, my sons buy, and anyone else I talk to or who read my posts will buy.  Mossberg used to be an honorable company that made solid products you could depend on, but it seems that has changed.  I hope I am wrong, and I tried to escalate via email but the representative I spoke with seemed very confident that it was not their problem and I was on my own.
Stay away from these, especially for home defense, they are not reliable and they will not stand behind them
