Well, if it were mine I would:
1. Get the mag extension.
2. Put some ghost rings on it.
3. Lose the pistol grips & folding stock. Replace with fixed stock and "normal " forend (or a surefire.)
4. Lose the side-saddle.
5. Arma/dura/teflon coat it.
But, it's yours - and you can do whatever the hell you want with it.
