Question on factory rear sight (Marlin)

[Ahsan Ahmed]

Much appreciate if anyone could let me know the graduation (if actually such) represented via each step of the (single step elevator) sight provided on the Marlin (Winchester etc) lever rifles?

More appropriately, how many steps up may possibly set the rifle for 100 yds......please bear with me if you do choose to respond as I am not entirely familiar with this type of rear sight and would like to work with factory irons and try to make that work before I install the XS ghost rings on my 1895G. Admittedly, too many rounds down range is not too good on the shoulders but tolerable all the same

Thanks,

I don't think the sights could have any sort of predetermined adjustment as there are many brands / loads / bullet weight of ammo for most calibers. Each different round would have different ballistics and the changes in the point of impact would vary from load to load for any adjustment of the sight. For example one step might change the POI 1" for one load, and 1.5" for another. Plus I would assume that marlin uses the same stepped adjuster on every caliber, not one for each specific caliber.

But if you are going to swap to XS sights anyway, why bother getting the rifle dialed in only to change the sights? I have the XS sights on my 444, and I think they are great.

Thanks for the input.....makes sense. Was wondering why Marlin provides such sights in the first place (cost efficient perhaps?) if those are not at acceptable standards? Well, I was planning on using factory irons this season at least but then again switching to ghost rings may be a better option since I've already got those.

On your present rear sight you would just have to try it. The traditional way to adjust that type sight is to get it to the closest sighting you can with the notches. If it is between notches, in other words if one notch is too low and the next too high, you have to us the higher notch and file it down until it is correct. To give you an idea of how much to file off, look at the figures below.
If the distance between your front and back sight is 18 inches, that means it is 200 times that distance to the 100 yard target. Filing off .010" would lower the point of impact 2 inches at 100 yards.

It also depends on what model of rear sight you have. There are 2 listed in my parts breakdown and I have just upgraded my Marlin/Glenfield to the better rear sight of the 2.
