I picked up the Lyman 17A (AMI .495 height) and installed it with no issues what so ever. Didn't even have to put a file to it. Drove the old sight out and drove the Lyman in. I'm glad I went with the Lyman because of the interchangeable inserts. Sight picture is much better.
Now I need to load up some ammo and go to the range and sight it in.
