I'm glad i've got the rail with the handle mounted to it. I'll be happy to streamline it and remove my handle/front sight when i put on the red dot.

It is a pricey stock (nothing compared to hard core ar15 fanatics favorites). There are quite a few really expensive parts out for these guns and most don't do anything special. If you are looking for the full auto feature and don't want to spend $15k for the regular m16 300 bucks isn't too much really. I'm not a fan of wasting ammo so i'll probably use it on semi auto most of the time but its nice to have it just in case.
