i really like the spikes and rra. if i find a complete for a nice price i will buy. i may try to find the uppers and lowers and just build it to how i want it. so im thinking a rra lower and a spikes upper or mega upper. i hear the stags lowers are nice as well. will see what the gun show has then hit up a dealer to see what they got. figured since its close to x mas things may go cheaper.
