Overall it has been a pretty frustrating experience. I hate having reliability issues. That said, PSA = good people. Buy with confidence - they stand behind their products and care about their rep. No one is perfect and every manufacturer makes mistakes.
Another 150 rounds through the pipe and feeding was 100 %. I contacted PSA to ask what they think, and they assured me it was just cosmetic. They offered for me to return it and they would fix it perfectly. As long is it is feeding fine I'm happy. Got it sighted in today - it shoots great. 
I was easily popping a 12" gong @ 275 meters off a bag. The damn FTE's are still happening though. I had 8 in 150 rounds. Brand new Pmags and D&H alum. I had 3 fte's in a row 
Palmetto is sending me a new extractor. 
This is my first AR that has the cuts. Is it ok for them to be a little off?

Shouldn't be a problem. But, go shoot it to be sure.

Does that barrel extension have M4 cuts or regular cuts?

Looks like a rifle extension in a receiver with M4 cuts to me. If not, that's the most pronouced misalignment I've seen.

Those barrel extension ramps look somewhere between a rifle cut and an M4 cut. (see attachment) 3. The barrel pin location is a little off which causes that misalignment seen in your pic. 4. The receiver is fine. 5. Who is the barrel maker ? Yeah, one way or another I'd fix it......I'm picky.

You've got the WORST luck going..
That is not good.. call them ASAP on Monday and send for an RMA label for that upper.. they will email you a label.. once you ship that one out.. they will send you another.. you seriously have 0 luck.. the B option is to dremel that even.. but I wouldn't.. its brand new.. |

I don't know PSA from Joe Blow, but any gunshop that would put that on the street and call it legitimate should be avoided. You need matching M4 style barrel extension for the M4 style upper. And, it is not like this is some kind of new problem. I think Colt came out with these early on to help solve the feed problems encountered on their M4 design, what? 5-10 years ago? I won't buy any AR-15 without the extended ramps now.

I like PSA, but that extension is a rifle extension and does not have M4 cuts. The receiver does have M4 cuts and that is not a good combo. They either need to replace the upper with a rifle upper or replace the ext with a M4 one.

Because, some of the third party mags had practically zero quality control (hard to hold mils tolerance on bent sheet metal). I am convinced that it was a worthwhile fix for even semi-autos if one wants to increase dependability of feed ie. avoid jams in the most critical situations. Back in the day we ran M193 and M855 with pointy ends. Now the meplats may be truncated (OTMs), soft points, etc. Also, now the case-to-bullet crimp may be a swaged style with blunt neck ends. These later tips and crimps are just looking for a place to hang during feed. |

simple test for the OP.. using a Qtip run it from the bottom of the feed ramp on the RECEIVER up toward the chamber.. if it SNAGS on the SHINY METAL barrel extension you MAY be screwed.. your pic is borderline IMHO.. that RAMP needs to be smooth... |
