Savage 23B rear sight

[BasinC]

Has anyone tried, or thought of trying, to put a Skinner "Lo Pro" sight on a 23B?
Not sure what the screw size or thread pitch might be on the top rearmost screw plug. I believe it's a '6' but the tread pitch ...

Since OEM sights seem to be unobtainable, and I'm not interested in doing a side mount, this might be a viable alternative.

The smaller screw is a common size, 6-48 or 8-40 can't remember which! The bigger screw is a #10. I have the same rifle but it came with a Lyman peep sight. The original Savage peep sights do not exist in this world! I don't see why a Skinner wouldn't work, just no windage adjustment!! You might have to mess with front sight height, too. I have Skinner's on several rifles. love them!!
I modified a Brownell universal dove tail sight base to attached to the existing peep sight holes, so I wouldn't have to D&T an original unmolested .22 Hornet. Put on a vintage scope!

I'm leaning towards it being a 6-40 right now. Tried that size tap, but didn't force it. Tried a 6-48 screw, that didn't go either.
The receiver hasn't been drilled & tapped for a side mount. I intend on keeping it that way. May just have to live with it.

I removed the plug screw from one of mine and as far as I can determine, (with cold fat fingers, old eyes) it's 40TPI. It's smaller than a #6 and bigger than a #4. The one I put the scope base on was of a later manufacture so maybe they changed sizes!!??

The earlier guns with two different size screws took a #10-36 and a #5-48. Later they went to two screws the same size with a closer hole spacing that are either #8-40's or #6-48's, I don't remember which. The #10-36 is the same size as used by Winchester for the front tang sight screw, those can be found, the #5-48's are a lot harder - Stevens used a #5-44 for tang sights and #5-40 seems to be available, but not #5-48's. I found a tap & die set for those and thread my own.

The Savage Model's 1904, 1909, 1911 and 1912 also used #5-48's to attach the barrel sight. These are all button head screws, so not much good if that type head will not work.

Thanks for the info!

Here's some information from another site on those screws - https://www.24hourcampfire.com/ubbthreads/ubbthreads.php/topics/12440884/making-screws-for-the-savage-5-sight-used-on-the-model-19s-and-23s#Post12440884 I also checked a later gun with the No 15 sight that uses two screws the same size, they are #6-48's.
