Opinions on this RIS rail

What do you guys make of this to fit to a GSG 5?

It looks like it has the hole for the push pin, provided that all lines up and I get a shorter screw for under the barrel, what else would it need to fit securely? I don't see a collar included.

Over here in the UK we're a bit stifled for parts without importing them from the US or massive price hikes.

Oh and there's 3 left apparently. Please don't buy them all before me!

-edit-

I see the forum removes the word, it's the well known auction site!
