Huh? The Mossberg 500 is the best selling shotgun behind the Remington 870.
I own two Mossberg 500s, one 12Ga and one 20Ga.
I also own a Mossberg ATR 100 in .243.
Hundreds of rounds through all of them, nary a complaint.
We did get a laser bore sight cartridge stuck in the rifle.
We sent it to Mossberg and they fixed it and shipped it back FREE within two weeks. I’d say that was excellent customer service.
They also included a letter that said if anything went wrong with any of their products in the future to simply ship them to Mossberg and they would be happy to fix it.
I’d buy Mossberg again.
