Rifle barrel blanks are manufactured in the barn, you overweening idiot? Steel for the action is manufactured there? Cartridge cases and primers are manufactured there too?
JFC. You win the prize for slack jawed yokel smug ignorance.
Yeah and Damascus steel wasn't produced until the 20th century because those dumb peasants of the middle ages were stupid.
Why do you think some of the equipment that was used 50 or even 100 years ago still operates? Think there's parts to fix them or do they have to be manufactured locally?
Do you know how to reload your own ammo with just a used shell case? Can you make your own powder and primer? How about manufacturing the shell case from scratch? Ever grind your own telescope lens? Think its that different from the optics in a high powered scope? Do you know how to use a metal lath and other equipment to create a replacement part from high quality metal stock?
For all your supposed smarts you're pretty frakking ignorant about the capabilities of someone who isn't college educated. After all you didn't see the red wave coming and if you had to grow a garden or raise an animal you'd probably die of starvation. You'd be lost and bewildered without your smart phone or the voice of your liberal leaders telling you what to do.
