Help identifiying this FF quad rail

[Thermal]

My girlfriend's dad had a box of misc. firearm items. This rail was one of them. Any chance you all could help me ID it?
The hex screws have Y F S stamped on the head.

You don't even shoot a picture to show the entire rail....? LOL, I know you can do better than that!

It is a cheap generic rail, not worth much, if you want any other info post a picture so people can see it in its entirety.

D'oh! Is there a "kick yourself in the butt" smilie? LOL
Thanks Stick!

Man, I've been looking for a while to see if I can come up with something, and no dice so far. The "YFS" is more than likely from the Fang Sheng Screw Company out of Taiwan. (http://www.yfs.com.tw/yfs_en/about.aspx?typeid=1&url=about1-1.htm). They are one of the world's largest socket screw manufacturers, so those screws will probably be on the mass majority of the rails made.

Were there any other AR parts in the bin that have a name on them?

I really didn't have a chance to look through the box, so I really have no idea. I was told however that there is an identical rail to this, just in rifle length. I'm going to swing by there this weekend and see what goodies I might find.

Look up Firefield. I saw one in my LGS today and it looked similar.
