There's a very small pin in the top of the sight next to the "clicker"(elevation adjusting knob), this engages in a depressed ring in the top of the elevation adjusting screw/metal thread. When that's removed you can wind the elevation adjusting screw out of the bit with the apature in it, and out of the sight. Be careful not to lose the plunger and spring, or plunger and bearing that are housed just on the other side of the pin you first drive out, these also sometimes need to be depressed a bit while you remove the elevation adjusting screw, as it may foul in the depressed ring in the top of the elevation adjusting screw/metal thread, and thereafter the threads.
What sort of 100 meter mod do you need to make?
It might be a better idea to put in a slightly higher foresight if the problem is that it won't zero at 100.

Here's a tip for all of you wanting to take the Mk1 sight apart. Do pretty well what TBonesteak has said BUT:

Get yourself a largish polythene bag and wrap the open end around your right wrist with an elastic band. Now cut a wrist size hole in the other end. Once you have driven the cross pin out, don't do ANYTHING ELSE EXCEPT put the sight inside the bag together with yoiour left hand. NOW take it apart because no matter how careful you are, the ball or plunger WILL come whizzing out and you WILL lose it.

Assemble in the same way but use a big dob of grease to hold it all in place. But at least when it does whizz out the first, second and third and more times, it's still there!

When you've done it a zillion times you can do without the poly bag. You always knew when an Armourer had lost one because it was always followed by the words 'bolloxxx' which I understand indicates 'Oh, deary me, I'm losing my patience.......'

Anyone got a source for replacement balls. If I remember correctly, they are the same size as model railway wheel bearings. They certainly don't use many in my Centurion

thanks gentlemen, my plan is file down the two lips on the bottom on the actual peep this will allow the peep to go down a little further giving me a 100 yard dead on mark. i just have to take her to the range to find that 100 yard mark and then engrave a marking.

my sight blade is good, the peep just doesn't have enough room to go down past 200
