I picked these up in a lot of some AK parts and am having a hard time identifying them.  I have previously been told that these look as though they were "bubba'd" with the scalloped edges?
They have a feel as though they would be a "hardwood" upgrade or something, but I do not know much about FAL/L1A1's... Does anyone know if there is anything special about these or are simply "bubba'd"?

Thanks in advance for the help!

Looks like somebody screwed some Aussie handguards.

Aussie was my call as well. so Yeah, Inch Pattern

+1 for Bubba'd aussie.

Thanks for the info guys. I'm trying to learn where I can.

I added another picture to the original post.  My links weren't working because I had done it from work.  Fixed now!
