I think you kept it pretty simple... just added functional stuff (well, maybe the flash hider was a bit over the top...). You didn't gob it up with junk from Cheaper Than Dirt, which is commendable.
You do need to get a decent tac sling for it, though. And if you shoot it a LOT, get the Magpul enhanced trigger guard to save your middle finger.
BTW, nice TRP... also part of my battery!
