I have one of these rifles and enjoy shooting it but want to bring it up to date a bit.  
It has a 16" bbl with 3 prong flash hider, don't know what make.   Imbel receiver and looks like PAC build.   Very nice rifle.
Furniture is painted green but thinking of duracoating it in FDE.   Just like that color a lot.  
I was thinking of getting  quad rails to give me a bit more options but what about furniture.
I really like what  I have seen with the guy using ACR side folding stock with that side folder adapter..   Gives the rifle a much needed boost and more modern look but not sure if I can justify the extra cost.   Guess I want to bring my rifle to the 21st century with minimal cost.  Instead of buying  SCAR17.  
So anyone have any suggestions on this subject matter.   I have seen quite a few pics of mods done but would really like links to sellers web sights that have these items.

Thanks,
Stac

DSA sells some of the things you are talking about.
Just google the part your looking for and see who has the best prices.

The only modern part I like is the extended selector made by DSA and a SAW grip.

Be warned, it may take some time for DSA to ship, after they charge your card of course.
I've always had the parts show up after some time.

Shooting through cover and concealement is about as modern as i need!!
