It's quite possible that the front sight tower was canted. That would explain the severe windage adjustment. They may have straitened the sight & zeroed, thus saying it "zeroed" fine for them.
As long as you can zero it & it shoots where you aim, problem solved...whatever it was.

I know Palmetto State Armory isn’t considered a top tier AR, but I thought I might share a recent experience I had with their warranty department. Just to give some context, I’m not a novice firearm guy. 23 year LEO, 11 of those years were spent as a pistol/patrol rifle instructor for my department. I picked up one of their premium mid-length FN barreled uppers equipped with an A2 front sight. Some time later slapped it on a PSA lower, with a detachable carry handle with the intention of making this an iron sight only rifle.

I took it to my range to zero it, but I could not get it to zero windage wise. I ran out of left windage adjustment on the carry handle. I took it out a second time and had the same result with the rear sight off my LMT Defender 2000. I contacted PSA and obtained an RMA for the upper, and sent it back. They told me the upper was fine, and they had no trouble zeroing with their rear sight, saying the problem was my carry handle.

When I received my upper back from PSA, I noticed marks on the left side of front sight, on the barrel, and gouges on the left side of the mounting clamp on the carry handle. It should be noted when I sent the upper back, I left the carry handle attached, and the rear sight as it was after my last attempt to zero. Meaning adjusted all the way to the left. When I received it back, the rear sight had been returned to center. I took it back to the range (same distance, same ammo) and was able to zero for windage with six clicks of left adjustment. It was obvious something had been done to my upper.

I recontacted PSA, included photos, explaining to them my observations with a request they explain to me how they fixed my upper. All I got back from them was an explanation of how they determined it was within spec.

Not sure what I’ll do with the upper now, maybe just remove the A2 front sight and go with a low profile gas block and an appropriate forend. Just wanted to give everyone a heads up in case they’re thinking about a PSA product.

I can understand not being happy about some scratches... but.

The rear sight that you wanted to use now zeros with the front sight within 6 clicks of mechanical center.

Ham fisted maybe, but they resolved the issue from a functional standpoint.


I always say, you can't see scratches on a gun when you are looking through the sights/scope actually shooting it.



It sounds like you had a FSB where the taper pins were not drilled perfectly, and you had a canted FSB. Somehow, they tweaked it closer to mechanical center. In doing so, they put some scratches on it.



Some photos of the marks and scratches would help determine how egregious it is.

I don't know how one would "tweak" a FSB closer to mechanical center. That would translate to bending the FSB. There's no fixing a canted FSB, short of installing a different barrel assembly, right? I suppose you could remove the pins, center it up, and then redrill oversized pin holes, and install new pins. That'd be an "out of spec" rifle though, at that point.

Maybe it was a matter of a poorly machined upper, causing a canted barrel assembly, relative to the receiver.

For sure, I won’t buy another PSA made anything. If may ask, what was the ultimate outcome with your canted sight?
