I recently purchased one of these M&P M7 bayonets new as a gift for a friend. The first time she unsnapped it, the snap broke. S&W's customer service response: since it's been discontinued, there's nothing they can do. So much for their "lifetime" warranty. I even own stock in S&W as well as in American Outdoor Brands, but after this firsthand experience, I'm wondering why I should. Clearly a second rate operation.
