Better than I do I think. I'm not a terribly good shot to begin with, and aligning the tiny notch in the rear sight with the spike on the front sight is super hard on my eyes. That's kind of why I want to mount a scope.
The longest range in my area to which I have access is only 100m. At that distance I manage 2.5'' groups with Sellier and Bellot ammos (groups are always high cause the iron sight is zeroed at 300m). But as I said, the carbine can probably do better than its owner
