JDL -
This is anathema for some AK purists, but I found the standard length stock on my AK to be WAY too short and replaced it with an adjustable stock. Here it is showing the length difference between what it was and my preferred length of pull. This made a huge improvement in the shootability of the rifle and I have gotten my 5-shot group size down to 1.6" at 100 yards using the iron sights and cheap steel-cased ammo.
