This is not a conversation about guns. This is a conversation about items that have withstood abuse that are near unbreakable.
Some items I have heard referenced as AK47 of:
Gerber MP600: It’s a multi tool
Old Thinkpad Laptops
Mag lights
Toyota Hilux


AR-15
Also, the 1911 class of pistols. Can’t go wrong with the OG Colt Government Model. As in, it can’t jam, fail to feed, fail to eject, fail to chamber, fail in any way.
Honorable mention goes to Hi-Point. Ugly and heavy fucking guns, but they function flawlessly and last forever.
You’re not wrong, but the discussion is tools and equipment, not firearms.
A firearm is very much a tool in some non-combat applications. Ranching, for instance.
