You can look at my pics that are in Tic00 WTS add on the EE that you recently posted in.  I don't know if it would work with a side folder or not.  I will know for sure when the rifle in the pic gets back to me with  a Russian poly folder on it.

nugentgl, please post pics of the setup when you get it back with the russian poly folder on it.  I saw the pics for this rail set on TDI's site a long time ago, but thought it might be a bit too big.  It doesn't look that way on your rifle as it is pictured.  I'm planning on several builds with those poly folders (I've got 6 of them now) and that rail set might go well together if things fit right.  I like it even better than Krebs fore end rails.

I had a Kreb's but sold it once I got this one.  I really like the rail that extends over the dust cover.  Makes running a site much easier.  I should have my rifle back mid next week and I will try to snap some pics for you.

I can only imagine how long before there's an air-soft copy or crappy knock off variant out there.   Looks like a great bit of kit.  Well done!
