Can I throw in another sight?
Have a good look at the Spot Hogg Hogg-it Hunter.
.019 pins round guard white strip for peep alignment.
2nd and 3rd axis gang adjustments as well as single micro adjustments on both windage and elevation.

It does cost a little more but IMO they are probably the best out there.

Here is a link to a place that has a lot of gear and probably the best prices.
