I had to remove the rear sight to install the Apex ultimate striker block assy. The rear sight was a real pain to get off. I tried lapping the bottom to smooth it out but was hesitant to go too heavy. I don't have a way of lapping the dovetails. Getting the sight back in was a trick too. I am going to sight it in this weekend but I think it will be really difficult to move the sight in small increments. On another post, I was told that 0.007" makes about a 1" POI move at 25 yards. I don't want to spend a ton of money on a sight adjustment tool. Anyone have any ideas or tricks for making the adjustment easier? Thanks.
I just got mine in the mail. Have had an APEX USB kit sitting here looking at me and finally bought this tool to install it.
I was done in minutes. Longest part was getting the slide masked up and then finding the right things around the garage to use as shims to get the sight pusher aligned (height is not adjustable.)
