Mostly wondering what im supposed to do with the tiny ball bearing and spring

[CINDERS]

A certain member on this site whom is very familiar with all types of sights and fixing them may be along shortly I gather to help you with your question for assistance.

Sight rebuilding tips are searchable (top right corner). Essentially - thread the micrometer screw into the bush in the assembled cursor & scale. Move assembly to large ziplock bag or assembly glove box (to stop the spring and plunger escaping). Put several spares of each in the bag and bang on after each one gets away (inside the bag or box). Spring in first, then ball - blob of grease makes them "sticky" and slows their attempted escape - trap against the micrometer screw shank. Depress ball / spring ( I use a section of an old feeler guage), advance screw "home" until the keeper notch in the micrometer screw shank aligns with the assembly pin hole (and the detent ball with the ridged crown on the micrometer screw) - put the pin in the hole!. I use an auto center punch to drive the pin... test micrometer function and clicks - Linish and finish pin to taste. Put extra springs and balls in a safe place until next time. Use safety glasses - not a second ziplock bag on head. Keep mouth closed throughout..

What is the thread title for the tips? So the spring and the springs pin go into the very top hole and then you put the ball in that same hole? Doesnt seem to be enough room for it

Or does the ball go into the hole where the tip of the screw screws into?

[wesman5060]

Scratch that I just need to know where the ball bearing goes.

There are two different methods of giving you the micrometer 'click' when you rotate the range adjustment spindle. Some rearsights were supplied with a little plunger that the tiny spring fits over (& both together fit into the little hole at top left of the sight leaf). Others have the spring, but have the ball bearing instead of the little plunger. If you have one of these sights you just need to seat the ball bearing on top of the spring in its little hole, with a blob of grease. Then do as L1A1 breakdown has explained.

Oh okay so either the ball or the plunger will work but dont use both at the same time?

I was supplied with both when I bought the parts set

Obviously the plunger is easier to set but which is better to use for a better click if that makes any sense at all lol

[browningautorifle]

which is better

Either is fine if properly lubricated. The US used lots of plungers to good effect, we changed after a time...

[wesman5060]

Lost the ball so plunger it is lol

[wesman5060]

Finally got it. Didnt have any grease so I used a piece of a razor blade to hold the spring in. The screw retaining pin was too long but I guess theres not much I can do about that. Thanks for the help yall!

Honestly kinda prefer the plunger to the ball. The clicks are a lot more easier and quicker than the ball in my replaced sight. But I guess that also means its easier to be bumped out of place
