We need a updated chart.
I bought one a few months back. Not quite as inexpensive as the one the OP is talking about but close.
I have a set on Troy fold downs on mine, and the rear aperture is definetly favoring the left hand side.
I thought I was the issue, but set it back to what appeared the factory placement and had a buddy sight it in, without letting him know.
Same thing, maybe 1 full revolution from not having further windage adjustment.
As a side note, it runs Federal Fusion MSR into a 1.30 group at 100M and for the purpose of this rifle, I am pretty happy with it.
Looking though standard AR carry handle rear sights, if the front sight appears centered is the gun good to go or can there still be some cant?
Depends on how bad the cant is. You really need an FSB alignment gauge to know for sure. And even if the gauge shows that it's off a bit one way or the other it doesn't always necessarily mean that the FSB was pinned on to the barrel canted.
Also interesting to note, you can indeed have a canted FSB and still end up shooting pretty well centered for windage. However, you can also have a perfectly centered FSB and still end up shooting way left or right for windage. In this case, a lot of guys claim that lapping the face of the upper receiver can bring your windage back to center, which may be true, but I have not tested that for myself.
The drawing specifies the front sight post threads' pitch diameter shall be true position 0.010" of a plane generated by the centerline of the bore and the center of the index slot in the upper receiver.
PSA seems to have gotten better over the years, and I own a few with very high round counts, and have never had a failure. They also have some really fun non-AR type guns as well. I think they're a good option for budget-conscious shooters.
In 2017 I purchased a PSA pencil upper, blem PSA lower and premium PSA BCG for the wife as a light weight range gun. I think the total was around $400. Shot nearly four cases of M193 through it without a hiccup. She has since lost interest... so whatever.
For those living snake-bit lives who can't seem to do anything without it turning to crap, PSA is probably not for you. But for those who aren't living under a dark cloud, they'll probably be pleased enough with PSA's inexpensive range guns.
Try their AAC (American Ammunition Company) ammo...about 1/2 the price of quality match ammo!
