Again I never said anything about whether they were designed to kill. That is a straw man that is easy to knock down. I own a handgun specifically for that purpose.

A gun designed for the needs of a soldier, specifically high volume, accurate long range fire is particularly well suited for shooting large numbers of people are long range. That is what infantry does. It would be pretty unusual for your home defense needs to involve this type of shooting.

The vast majority of home defense shooting involves close range shooting.

In comparing it to a car company I would compare it more to a car company that equipped a car with a solid bumper like what they put on demolition derby cars.
