I find myself perplexed by people who point out bottom rung firearms, are these the same as bottom rung vehicles? There is no issue with someone purchasing something they can afford, it may in fact mean the person has some common sense.
This thread is filled with analogies, but I'll entertain this one...
Using the car example above, let's say you have $5,000 for a used car. There's a Geo Tracker sitting next to a Honda Civic. You tell the Salesman you are looking for something to play with on some dirt roads. What you really wind up using it for is a daily driver. The guy sold you on the high points of the Geo Tracker, but didn't tell you that you never see them on the road anymore (hmmm, I wonder why that is?). You had two very different options and chose the Tracker. You could have had the more reliable day-to-day driver in the Honda. To quote Homer Simpson: "DOH!"

A lot of responses here have focused on WHY someone would want to own one. That's really not the question at all. When the person being asked is an owner of said style of rifles, it isn't a question of
why to the one trying to help and offer advice. It's a question of
HOW the potential buyer intends to use the rifle that should drive the choices. If the focus is on
why and not
how then one will wind up buying a semi-auto mag-fed rifle just to make a political statement and not to actually fulfill a role. It becomes an issue of wasted money vs. smart shopping.
As for the comments hinting that those of us who would rely on mag-fed semi-autos are mall ninjas, consider this: The very second one decides that a firearm is a go-to weapon for defensive purposes, then that firearm is no longer a range toy. It is relied upon day-in and day-out to serve that purpose, even if it never gets called upon for that use. Did you choose it and set it up for that purpose? If it has an optic or light, did you choose trustworthy auxiliary components or the cheapest ones at the local gunshow? If people take the same forward-thinking approach to shotguns or pistols, how does is not then apply to the mag-fed semi-auto rifle?
