Palmetto State Armory AR’s - I’m impressed

We need a updated chart.

We have 2 PSA uppers, and a BCG and some small lower parts in another gun, they're fine.

Gun I shot today was a PSA upper, I was hitting steel with it just fine, as usual.

How many clicks over did it take to zero your buddy's gun, windage-wise? PSA is notorious for canted FSBs.

One of our 2 uppers was like that. Still zeroed, but something like 21 clicks over, I think. ( I fixed it the fun way...ground it down into just a gas block, put a rail and MI front sight on it. Fun project and it's better in every way, shoots tighter too, being free-floated.)

Other was fine, zeroed within 5 clicks L.

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?

A little cant is normal, but not to the point that you can’t zero the rifle.

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.

It's funny, the chart is what brought me to M4carbine.net. I was in "US Autoweapons-LGS) in Scottsdale and they had it printed out and said, check this out. It was great for a newbie like me.

Try their AAC (American Ammunition Company) ammo...about 1/2 the price of quality match ammo!
