I've got an '03A3 that shoots into a nickle sized hole at 50 yds. My problem is the rear sight adjustment. Currently it is shooting 1" to the left, but just 1 click right moves the impact 2" so it is shooting 1" to the right. I thought the WWII rifles were supposed to move the impact 1MOA per click. I'm frustrated because I can't zero the rifle properly. Is the '03a3 rear sight really supposed to move 4 MOA per click?

You've got it right in both cases. Armorers in the old days had a push device, like a C-clamp, to move the sights. You told the armor how many clicks left or right were needed to zero, and he returned the sight to zero, then used his sight adjuster to make a corresponding adjustment so the rifle was on target at 0 windage.

To the best of my knowledge, one click of windage on an '03A3 was worth 1MOA. The windage marks on the '03 rear sight base were worth about 4MOA each.
When you turn the windage knob on your '03A3, are the clicks positive and distinct? If not, the detent spring may be worn. Sometimes you can removed the knob and add trying bending the spring to put a little more "curve" into it.

Nope, windage clicks on the 03A3 are 4 MOA.

As above, here's what the 28 September 1943 Ordnance description set down for the Remington 1903A3:
"Each division on the windage scale changes the point of impact 4 inches per 100 yards."
"Each division on the windage scale changes the point of impact 4 inches per 100 yards."

Well, belay my last... I stand corrected.

Losen the retaining screw and drift the sight, then tighten it back up.
Thanks for all the replies. I downloaded the Ordinance Manual for the 03A3. It seems you are all correct. Each graduation line represents 4moa, but it is supposed to take FOUR 1moa clicks to get there. See pic below.
I took apart the rear sight and bent the spring with the bump to give it more tension on the windage adj. screw. I now have four distinct clicks, one for each 90 degrees of rotation.

Vern, its been a very long time since I've taken off my whole rear sight assembly to do essentially what the OP wound up doing. I haven't even shot it for decades but looking at it not long ago, I want to center the whole unit better.
Are you saying that there's a screw pinning the housing to the receiver under the aperture? Or can I just drift it without removing the aperture assembly?

Ah, right you are.. thanks! Mine was all the way down and about all the way over so it was well hid. By any chance do you know what driver type and size that is? it's pretty cruddy down in that dark hole.. need to blast it out with some brake cleaner
Mine doesn't seem to have that slotted screw to the right in the top picture..
It's a Remington 345xxxx
