Does anyone make these?

I am looking for an airsoft version of this gun.

I dont believe any specific brand makes a model that resembles this. However the parts are available to make your own or at least something similar.

Take an M4, remove the stock, get that rail setup and walah?

You could just get a normal HK 416 and remove and add the parts you need to make that pistol, Or you could build it out of parts.

Looks like a 416 without a buffer tube and a CQB front-end installed. Be easy enough to replicate.

Only issue I see is the front RIS is shorter than a normal 416.

I like the stubby silencer on the real one.
