I'll have to post a pic later, but I bought the ARMS #18 Mount for my S.A. M1A Standard and attached it as instructed and even mounted the Nikon 6X42 to it. I then realized the rings I had bought, Xtreme Tactical aluminum 3-screw rings, were too thick and didn't allow the scope to be brought far enough to the rear for me to see through it properly without having my face all up onto the receiver. So I removed the scope and shipped the rings back to MidwayUSA to exchange for some Millet single screw extended steel rings.
Anyway, whilst handling my M1A with the ARMS mount still attached, and looking down the sights I noticed that it is tilted to the left some minute degrees and also canted to the left off the bore centerline. Now if I can notice this discrepancy with the naked eye, I would have been perplexed at the range trying to sight in the scope on that mount.
As this is my first experience with any M1A mount, I didn't expect to experience this "lack of quality".
Has anyone else noticed this with their ARMS? Has anyone had problems sighting their optics in with it? Or is this just a quality fluke with me?
I also understand this is an approved mount for the military and that they use them and they supposedly have a NSN number for the military equipment catalogs.
Could it be that the receiver isn't machined properly?

It's not the A.R.M.S. mount lacking quality.

It's very likely your receiver.

The A.R.M.S. mount is designed to fit the mil-spec M-14.
Lots of SA M1A's do not meet mil-spec standards.

My hunting buddies son has been trying to mount a scope on his Springfield M1A for about a year now.

Every mount he has bought so far ends up crooked, because the investment cast receiver is crooked.

Do you see the misalignment in the pictures I posted?
The rings I ordered are adjustable for windage, I'm hoping I can at least get the scope aligned down the center as best as possible, I can then adjust the crosshairs as needed to get it the rest of the way aligned, but I still think it'll be a solid setup when done, just not as initially aligned as I'd like.

That is really bad, send it back to SAI it is your receiver geometry. Make them fix it or replace it.
