Built-up gun

A built-up gun is like a toy gun that you can assemble yourself with different parts. It's not a real gun that shoots bullets, but it's made to look like one.

The "built-up" part means that you start with a simple frame, usually made of plastic or metal, and add different pieces to it to create a more complex gun shape. These pieces might include things like a magazine (which holds pretend bullets), a trigger, a barrel, and a sight to help you aim.

One fun thing about built-up guns is that you can customize them however you want. Maybe you want a longer barrel if you're pretending to be a sniper, or maybe you want a bright green magazine because that's your favorite color. You can mix and match different parts to make your gun unique.

It's important to remember that built-up guns aren't real weapons and shouldn't be used to hurt anyone. They're just toys for pretending, like dress-up clothes or action figures. Always be safe and responsible when playing with any kind of toy or game.
