Question about detail on ST

[Dropshipbob]

I don't know what the gun is called, it's the short one with the foregrip and it has a little bit of red on it.

Is that type of gun supposed to have red on it? To me, it's kinda distracting.

It's an MP5 K-PDW, or is supposed to be. The selector options on it are in red paint, but it doesn't have the triangle or line.

I kinda like it, gives it a 1980s feel to it. If only it wasn't so small.
