What rear sight?

[amadeus76]

For a No.4 Mk1* rifle, what rear sights are correct? Would the milled micrometer sight be kosher?

They are ALL correct.

I expect this will be an easy one for Peter et al - I was shooting my No4 Mk 1(T) with iron sights on Sunday, for the first time. I found the adjusting screw which elevates the slide has a "rotational floppiness" about it and not a definite click as it goes round.
What do I need to replace, in what sequence do I take it apart, and what goes wrong when doing it the 1st time?
I attach a diagram of the parts to help the explanation make sense to me...

what rear sights are correct

If you'd asked what originally came mounted...it would have been the one pictured by RobD below.

What do I need to replace

I'd say they all have a certain amount of slop. I'd just change sights. Or use a PH 5C for target and then change back to the other when it's not needed...

Thanks Peter, I shall follow those instructions.

I didn't want to replace the original No 4(T) rearsight which has its ground-off battle sight. Hence my wanting to fix this one up. Yes yes Peter I know it would be OK in your hands but I am a sentimental fool...

As for a target sight: I use the PH 8/53 sight, which is a quick fit to the original rearsight.
I had even hoped it would flip down and allow the No 32 scope to sit above it - but no such luck - even with the eyepiece unscrewed the 8/53 sight body prevents proper seating of the telescopic sight.

I am sure Peter has mentioned a few times about a certain little arrangement (4 & 5 ?) that acts on the indents on the thumb wheel apparently it is a right little sod to fit up

[Peter Laidler]

Just as Cinders has mentioned. You need to replace the detent spring and the plunger (or ball). And guess what's going to happen......? Yep, that little ball or plunger and/or spring are going to whizzzzzzz off somewhere. Suggest that you take it apart inside a large plastic bag and assemble it the same way after having cleaned it with a dob of grease on the spring and ball.

After you've done a zillion of them it gets easier. I used to hold the leaf - 2 in a vice with the spring hole upwards. Put greased up spring in hole and ball on top of greased up spring. Shape a piece of thin shim into a squared off U section and pull the ball and spring into the hole. Press in the adjusting knob -8 secure and pull shim out then test.

You could also replace the pin - 3 if it shows signs of wear. Because the wear allows up/down endfloat of the cursor -7

For a No.4 Mk1* rifle, what rear sights are correct?

Did you intend to say, what rear sights were originally fitted by the Long Branch and Savage factories to the No4 MK1* rifles which the 2 plants manufactured during the period of WW2? Was the micrometer adjustable rear sight originally fitted by the 2 factories to the No4 MK1* rifle during the WW2 period or would this sight have been retro fitted to this rifle (MK1* version)?

[Peter Laidler]

Nope...... I didn't understand it either! What Mk2* are we on about?

[browningautorifle]

What Mk2* are we on about?

No one asked about a Mk2*, that's why. Both of their questions were clear...
