There's a nut and clamp from a detachable carry handle, front sight post w/detent & spring, two taper pins, gas tube roll pin, and two other springs I know came from a bushmaster AR but I forget exactly where. Look close at the pic to see what you get. I could try to total what each of these exspendsive little buggers cost to order from the factory, but well... that would be retarded.
I'll take $13 plus $2 shipping. Pay Pal preferred because it so darn easy.
BTW- Not shown in the pic is a little silver ball from one of the spring detents that rolled the F' off to no man's land just as I took the pic. Well, I found it so you get that too.
