Hi all. Does anyone know how to get hold of the above? These are full size replicas made of rubber.

I have a full sized M-16 "rubber duck." It's actually made of resin. PM me if you're interested.

I'm more interested in WW2 stuff actually, 18Bravo, but where'd you get your M16 from? I've never seen one of these rubber guns up close, so do they look real?

From five meters away I wouldn't want to bet it wasn't real. Some have worn barrels in them, so the barrel and front sight post assembly are actually real. I actually have two, one black and one in desert cammo. They used to be available from some place on post called TASSC or similar. I've also seen them in surplus stores. We even used an M4 rubber duck in HALO school for combat equipment jumps.
I use mine at home for weapon PT and rucks. The local gendarmes know they don't have to stop me anymore.

Try doing a Google search under replica firearms. I've never heard of WWII rubber ones. What are the gun laws like where you're from? Perhaps you'd prefer something like this:

Where I am, it's not possible to own infantry weapons or even replicas. No handguns either. But I'll be moving to Germany next year and replicas are cool over there.

Is that an airsoft Grease Gun?

ummm... No.
This is what happens when there's no adult supervision. It's the real thing-note the casing in the air. We later actually shot skeet with it, and were successful exactly twice. Here's a friend of mine on an M-14 that same day:

Whoops, missed the casing. No, we can't own anything like that here legally. Nor in Europe. Which is why I'm looking for replicas. Here's one of me with the real thing, though, a few years ago. Chinese T56. Pic's a bit tiny but anyway.
