I've been very happy with my PSA upper. Runs like a scorched ape. Eats everything I've fed it so far, even dirty Wolf. Quite accurate. 5.56, chrome lined, 1x7, etc. Everything you want in a business gun. Think I paid less than $500 for mine including b/bc/ch. Palmetto did send my upper with the wrong color hand guard, which they happily rectified by sending me an appropriate replacement. And there was an issue with the fit of the hand guard. Sucker was really wedged on there. Was either an out of spec hand guard cap, Magpul's production run for that batch of hand guards was slightly off spec, or the FSB was mounted a bit too far to the rear. They offered to take the whole upper back, but I'm a handy guy and had it squared away in less than 30 minutes.
Depending on what you want to hang off your rifle, you may not necessarily need rails. There are kits out there that you can use to mount things to a Magpul hand guard.

I would like to put together an AR15 also, using the USM4 lower (for the crest and support of SF Assoc). I just want a reliable gun. I am not concerned as much with precision long range accuracy.
What is the most cost effective prebuilt upper (no sights, optics or carry handle-just upper with barrel, charging handle, bolt carrier group and rails)?
