I ordered a spare from Numrich.
It is the tallest, as my rifle has the tallest, and still shoots a tad high, but actually centers a 200yd bull when on 200yd position. I ordered some other items too, otherwise shipping would have been more than cost of sight blade. BTW, mine came "undrilled", so would require pin hole drilled.Sight protector is just that, with protector on, I can't see target under it, so can't shoot with it on.
