No I still have the OEM stock but I like the idea of a folder - hence my interest isn't the KDG stock.
I use the SCAR as a heavy carbine with a Trijicon accupoint 1-4. the only changes I've made have been a Tango Doem BG -17 grip and arail extension. I had the PWS 1913 rail extension - worked fine but made the rifle a little muzzle heavy with a light mounted. Replaced it with the KDG MLOK extension which I love, handles like a whole different rifle.
