Mr. Bane,
What you need is a PTR-91! Yes the H&K's will thump the heck out of you, JDL changed the number of flutes in the PTR and that stopped, recoil is as mild as one could ask from a 7.62 NATO. The heavy target barrel also makes the weapon balance better than the H&K and allows the use of lead bullets which were a no-no with the polygonal barrel. The sights are improved versions as well with windage adjustment on the rear.
Add a low mount scope mount

Of course you might convince one of your industry friends to start making Namibian stocks (hint-hint). Or you might just have to deal with it.
The PTR is the best of the H&K/CETME rifles around and the H&K/CETME is the best TEOTWAWKI, Road Warrior weapon you can have. It will fire anything, it just about never breaks and it spit bullets under conditions that an AK would sweat over.
They also happen to be on sale at a certain dealer, which I will PM if you want as I don't want everyone here buying them up before I can get one.
PS for a pic of the Namibian stock
