The one hole that isn't centered is because when you flip the sight, it moves on the screw. The hole is offset to make up for the movement.
A1 rear sight not centered, used an A2

One of the apertures for the rear sight is not centered. It didn't affect me as I was going to use an A2 rear sight. I highly recommend using an A2 rear sight, they're better. [PN: URPA2RSAP] Just a heads up, order some extra pins for the rear sight as well. I split the one during installation. It's the same pin that is used for the standard AR charging handle.

bought for my a1 retro and it was perfect. fit , finish and installation went without a hitch, all but lower , stock, handguards and slipring came from jse and it is coming together wonderfully. fact is all but the barrel is assembled and I plan on it in a couple of weeks. many thanks jse for having what I needed.i had the lower , buttstock and handguards from a few yrs back when I was planning this build, they are Vietnam era surplus. fact is my wifes health failed and I had to put it off till now. don't worry about jse quality its top notch.
