Yes, I'm sure this system is going to wonders for my abysmal split times.

No, the AK is preferred around the world is because it's stupidly cheap and if you can't find some of the millions in existence, you make one mostly out of sheet metal and rivets. On top of that

There are people across the spectrum that believe in private firearm ownership, however the overwhelming majority are found on the right. I'd say 80 to 90% of gun owners are right leaning.

Didn't you watch Die Hard?

Then he doesn't understand the law at all. You can make your own original design and build it so long as you aren't selling it.

And they totally exist.

Not quite, I have a full auto(M-16) carrier in my rifle, even though my trigger group, safety, and receiver are not capable of supporting automatic fire.

Are you fucking kidding me? Half the gun nuts I know are fast approaching the fringe right and love the police state so long as the police state applies to everyone else. Most of them are moderates but they are single issue voters when it comes to firearms, the rest either libertarians or left leaning.

I don't think an NICS denial is grounds for prosecution considering the frequency of false positives and people not having any idea why they are being denied. The real prosecutions result from straw purchases and lying on the form 4473.

.223 isn't a military cartridge. 5.56x45mm NATO is a military cartridge. .308 isn't a military cartridge, 7.62x51mm NATO is a military cartridge. The whole idea is fucking stupid anyways, since god only knows how many popular, common cartridges have been used by the military at some point. On top of that, the politically motivated could just direct military procurement to outlaw every new replacement round. What? The military made a spec for a rifle cambered in .247, gave it a designation, and had a single unit produced, and kept for special purposes? Fuck you for not having 1000.00 laying around to start reloading.

You need a deep hole drilling machine to ream out a barrel, not a lathe.

That's because fully automatic weapons are regulated by other laws.

A lathe might work for a pistol, but for any rifle that uses a modern cartridge with modern powders, a lathe isn't going to cut it.

From what I can tell, a rifled barrel is the most difficult part of the gun to manufacture, the machines used for it are expensive as hell and the process is time consuming.

Well the good news is that we can't reliably make all plastic cartridges, let alone all plastic weapons,. On top of that, people with access to a CNC mill have been quite capable of machining a rifle parts out of billet for years(Specifically the controlled part of the weapon). Yet the world hasn't fallen apart.
