I would say in .22LR for an AR style rifle @ 25 yards, 4 MOA (1 inch group) should be your maximum, with 2 MOA (.5 inches) being your target. I would say anything better than that and you're trying to use the wrong tool for the job. Sure if you put a long heavy match barrel on an AR and use match ammo you'll improve the accuracy, but you're starting to make the AR look more like a Match 54...
I find the copper wash ammo works brilliantly in my AR15, but it isn't match grade ammo and the problem with match ammo is it doesn't always cycle the bolt because of the lower fps. Whatever you decide to buy, I would say the weakest link is the quality of the ammo in a semi-auto, not the rifle itself.
I'm not sure why we would come to expect .5MOA at long range, but not at short range.
I understand that this isn't really the tool for the job of ultimate accuracy, but it is claimed that the .223 can obtain .5MOA, so why not the .22lr.
It would need to reach around 0.5MOA to shoot competitively, realistically. At least according to my calculations, which might be way off...
For example:
On a 25 yard target (10 spot) the bull is 12mm across and is inward gauged.
With 5.6mm of this area being taken up by the bullet itself.
Now if we go from the target centre and go 0.125" (half the red line shown on diagram) out and place another hole. it is touching the line.
same again in all directions (shown on diagram) This is the maximum possible variation you could expect and still be able to shoot competitively.
I'm not sure whether this is 1 MOA as I have shown the spread in both directions though... I'll be the first to admit that I'm not absolutely spot on when it comes to understanding the intricacies of angles involved.
If this is the case, then I would be after 1MOA or better, preferably around 0.5MOA ...
