What's the 'rail system' on Knex guns?

It is/was a rail system on Knex guns where you can put attachmens on. 

I don't know for sure, but I think it was MegaMetals' or rec0n's?

There are numerous kinds of rails for K'nex weapons. Builders tend to use what works best for them. Because absolutely no attachments serve any purpose other than aesthetics, we aren't really worried about standardizing a rail they all could attach to. However, there is also a way to attach real firearm/airsoft rail accessories to K'nex via the way I showed on the PDR, which may serve a little more use.

Hmm... Ok then. Thanks for the answer. Do you have a link for your PDR?
