In most cases, “AR‑15 switch” is slang for an auto sear or conversion device that allows an AR‑15–style rifle to fire continuously with one trigger pull, instead of one shot per trigger pull.

Key points (high‑level, non‑technical):

• A standard AR‑15 is semi‑automatic by design
• A so‑called “switch” attempts to make it fully automatic
• This turns the rifle into what the law classifies as a machine gun

⚠️ I can’t help with how it works, how it’s installed, or how to get one.

Is an AR‑15 Switch Legal?

In most countries, including the United States and many African nations, these devices are:

• Illegal to manufacture
• Illegal to possess
• Illegal to install or use

Even owning the device by itself (not installed) can lead to serious criminal charges, including long prison sentences.

Why the Term Is Misleading

• AR‑15 rifles do not have a “switch” like video games or movies show
• The real military version (M4/M16) is a different firearm, not a modified civilian AR‑15
• Social media often uses the word “switch” inaccurately for shock value
