Just an observation: Theoretically, on a 10-22 you can't get the aperture close enough to your eye w/o a long, wobbly extension. You'll not be able to utilize the potential accuracy of the .920 barrel with the "peep" 8-10" from your eye.
I have had the same thoughts about the rear sight placement. I measured the distance from my eye to the rear sight on my Winchester Model 52 which is unquestionably an accurate rifle and found it to be right at 6 1/2". Using the Weaver mount on the 10/22, a sight placed at the rear end/last notch of the Weaver mount will also be about 6 1/2" from the eye. The rear sight peep on the Winchester Buffington style sight is quite small but still very efficient. So, a slightly larger rear sight peep should be a bit more useful, at least in theory. I will probably use a Lyman 17A front sight, one that has interchangeable inserts. I like the one that is an open loop that allows for centering the target in concentric circles, something that the human eye does naturally. The search goes on!
