There's a company coming out wth a new AR stock that resembles a PSG-1 stock. It has adustable comb and LOP. It even has a point to attach a bi-pod on the base of the stock at the rear.
It's due out in the next couple of months I believe. I just can't remember who it is who's putting it out or where the thread is.....
I'd kiss ya if you weren't so damn ugly!
