A recent study published in the Proceedings of the National Academy of Sciences reveals that across all political and social groups in the United States, there is a strong preference against living near AR-15 rifle owners and neighbors who store guns outside of locked safes. This surprising consensus suggests that when it comes to immediate living environments, Americans’ views on gun control may be less divided than the polarized national debate suggests.
The research was conducted against a backdrop of increasing gun violence and polarization on gun policy in the United States. The United States has over 350 million civilian firearms and gun-related incidents, including accidents and mass shootings, have become a leading cause of death in the country. Despite political divides, the new study aimed to explore whether there’s common ground among Americans in their immediate living environments, focusing on neighborhood preferences related to gun ownership and storage.
Then why do people buy the top one over the bottom one?
I can’t answer for “people,” only for me. But I’m pretty sure you can’t just slap an upper receiver for a different caliber on a Mini 14. The AR platform is inherently customizable and modular.
That doesn’t make it shoot bullets any harder, though.
What’s the practical purpose of changing calibers if it doesn’t make a difference?
Changing calibers absolutely does make a difference. If it didn’t, we wouldn’t have so many. My comment about not shooting bullets harder has the implicit clarification that this is if it’s chambered in the same caliber as another gun.
In their default factory configurations, the vast majority of AR-15’s as well as the Mini 14 (the other gun pictured there) fire the same cartridge in the same caliber with approximately the same amount of energy, to no appreciable difference whatsoever from the point of view of whatever was shot with them. That is .223 Remington.
If you convert your gun to a different caliber, obviously the comparison no longer applies unless you compare it to other guns of the same caliber. But the Armalite platform is very modular, so making that conversion is super easy. This allows you to, just as an example, buy a bog standard model chambered in .223 and leave it that way for self defense or whatever, but then get an inexpensive .22LR upper to fire cheap .22LR ammo for target practice or plinking without having to spend the entire GDP of a third world country on ammunition, and/or keep a larger caliber receiver on hand in .300 Blackout or .450 Bushmaster or similar for hunting.
This saves you from having to buy and secure three separate guns for three separate tasks, especially considering you’re unlikely to be needing all three at the same time. (I don’t know about you, but I only have two hands.)
I think most gun owners tend to own quite a few guns. I also have seen where people tend to buy multiple AR-15 rifles in order to build something different every time for no discernable reason other than they like to build them and show them off. The issue is that the AR-15 platform attracts certain kinds of people who really don’t have an interest in shooting as a sport. If it wasn’t available I would guess that many of those people wouldn’t buy some other rifle in its place.
The short answer is that AR-15s are just better rifles. They’re more accurate, they’re more reliable, they’re easier to clean and maintain, they’re easier to repair, they have much better ergonomics, none of the parts are proprietary, and consequently there’s an enormous aftermarket for parts, accessories, and customization. They also have a modular design that, with the exception of the barrel nut and castle nut which have torque specifications, can be almost completely disassembled with a single roll punch and an allen wrench or two. That means if something breaks or wears out you don’t have to send it back to the manufacturer or pay out the nose for a gunsmith, you can just order the part and fix it yourself with basically just a pointy stick and a YouTube video. It also means you can start out with a really cheap rifle and upgrade it component by component until you have a high-end rifle if you want to.
That Mini-14 on the bottom is a fine rifle, and they’re actually pretty popular, but the AR platform outclasses it on most crucial metrics. If you could only have one or the other, for most people it’d be the AR without question. A lot of people have spilled a lot of ink speculating about this reason or that reason as to why so many people want ARs, and usually manage to miss the fact that they’re just fantastic rifles. Even with the amount of cringey fetishizing of the military that happens on the conservative side of the gun community, nobody would want one if they sucked.
