Various sight units can fit, so yours might work better with a plunger, it should not be spring direct on blade if you think about it logically;

Ed, The only problem with the pattern elevation wheel, is that they have diamond knurling on instead of the parallel knurling of the original. Such a shame, and an issue that could easily be put right. Not sure why they do it that way ??

Hope you are well.
