The boob tube emits harmful XXX-rays

there are probably good reasons why First-World nations are adopting all new rifles that use more proprietary short-stroke systems
It all ultimately comes down to unit cost.
Contrary to what US market prices might have you believe (and the worst import laws in the world help keep foreign gun prices high), AR-15s are one of the most expensive modern rifles to make- they require more machine time and labor than any other modern rifle. Sure, forging helps get the rough shape right and saves a good chunk of process time, but you still spend a lot of time drilling and tapping holes and milling into that final shape and that gets expensive fast.
Every modern rifle is made this way. They're not nearly as outwardly blatant about it as the Bushmaster M17s is, but aluminum and plastic extrusions require vanishingly little post-processing time: the tubes need to be cut to length and have a few holes cut into them, and the plastic lower assembly needs nothing else (if it needs to be made in 2 halves, like the KE15 does, it can be automatically welded closed). Install the other parts (doesn't require trained labor, even for the barrels most of the time) and the gun's out the door. The upper half doesn't even need to be aluminum if you're smart about it (Beretta was, HK was not) which means even less cost and weight (for the cost of significantly less sustained fire capability and slightly less durability, like the AR).
So why's the AR not made that way too? Because you can't make an AR any other way without losing its unique advantages. The BCG and buffer has to sit where it does mainly for balance reasons- all piston guns except for the AR are front-heavy, and because they usually pack on a pound and a half for reasons related to that aluminum extrusion the balance is worse than a similarly-equipped AR. The Perun X16 is a really good try, but I think most reviewers are confusing more weight with better overall handling. This isn't even something the KE15/WWSD solves, being that it requires more reinforcement material because the stock and lower are one unit and, if you're not using the thinnest barrel and lightest forend you can manage, compromises the balance just the same.
This website is a place for people who want to move past shady thinking and test their ideas in a
court of people who don't all share the same biases. Our goal is to
optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.
The weekly Culture War threads host the most
controversial topics and are the most visible aspect of The Motte. However, many other topics are
appropriate here. We encourage people to post anything related to science, politics, or philosophy;
if in doubt, post!

Why are you called The Motte?
A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently,
it's an element in a rhetorical move called a "Motte-and-Bailey",
originally identified by
philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial
but high value claim to a defensible but less exciting one upon any resistance to the former. He likens
this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for
the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired
propositions to which one retreats when hard pressed."
On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
New post guidelines
If you're posting something that isn't related to the culture war, we encourage you to post a thread for it.
A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts
such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a
submission statement. A submission statement is required for non-text sources (videos, podcasts, images).
Culture war posts go in the culture war thread; all links must either include a submission statement or
significant commentary. Bare links without those will be removed.

You know what's dirt cheap by contrast? Aluminum and plastic extrusions.
