I agree with you on the factory opens on the BL-22. For very young eyes, I think they allow very fine sighting, but I just couldn't see that tiny front bead in that tiny notch against anything but a white background. But I am absolutely satisfied with the Skinner set up, though I want to make the front blade more visible against a dark background. Still, as is, it is a hitting combination. Friend and I, after bird hunting last month, went to work on the smaller branches of a dead ash tree at 25 yards or so. If was so fun clipping off those finger size twigs 2" at a time that we used up a box of 100 shells and would have kept on if we had more ammo.
