Ok need an honest opinion. I'm very seriously looking at this upper from PSA. $300 fully assembled with free shipping. With iron sights I think it would be a good jumping off point to get the feel for things.
I second that. You haven't seen sloppy until you've seen ptac. I've since quit getting any PSA parts, even tough I hade some stashed. The few components I had got gone very quickly. The difference could be seen and felt...
