well some people do park with sight in place

there is a 1/16 pin in the sight windage knob. use a small starter punch to start the pin out, most knobs are staked on both ends, then use a standard 1/16 punch to knock it out. remember when going back together use the 1/16 punch as a slave pin so the pin will go in easy for the most part, locktite or restake....

other than that is is straight forward
