AK receiver rail question

[tormentor]

I have been looking for a receiver cover with rails for my G&G AK103 to put a red dot sight on it, but after doing some research on a few of them, they all seem to have some fitting problems for different AKs. I have seen 2 or 3 people on the forums with one, so pretty much, I'm just wondering what brands will work for airsoft guns. If you're wondering what I'm talking about, it's this: www.amazon.com/NcStar-AK-47-SCOPE-MOUNT-TRI-RAIL/dp/B000G97OJ0

I got mine from EbayBanned for $50.00. It fits over the reciever's top plate and is secured into the stock via a single screw.

CYMA also makes a full reciever rail, but it has a different securing method.

Generally anything from NC STAR is ugly, cheap, and civvy.
