I'm sure I've seen sight spacing blocks somewhere, but now I feel the need for one I can't find them! Anyone know of a source, or an alternative? The problem I have developed, and I'm not sure how, is a loss of windage adjustment to the right - I'm pretty much wound in as far as I can go which is fine in normal circumstances, but if wind dictates further adjustment I'd have to aim off to compensate. That raises another point, does anyone feel that aiming off is the better option anyway, rather than chasing ever changing sight marks?
