i would keep an eye out for a PSA deal. they can be had if you just keep looking. i picked up this one a couple months ago. No hand guard, BCG, or CH but i picked those up pretty cheap.

i will add that i have a nice piston upper for my SBR but wanted a cheaper one with a FSP that i can use as a "beater" with just iron sights and it has fit the bill. this one has eaten everything i put in it with no problems and i abuse the crap out of it.
