Looks like you had fun. I always like things with a personal touch, even if I don't necessarily like the end result: not so in this case, though.
The mag holder is a nice touch: always handy as a time-saver if nothing else, and the stock as a whole looks very nicely done. A neat, well-thought out package. Well done you!!
So, does the new stock improve your aim, comfort, both? Or purely cosmetic? Why the switch?
