I came across a 46M B with the s107 on the barrel and the s130 on the receiver and first thought that someone added the receiver sight along the way. Then I noticed here in the Sticky section that they came with both rear and receiver sights. Does anyone know why? I much prefer the receiver sight and find that the rear sight just gets in the way. Can anyone offer insight? Also, anyone removed the S107? Is there any more to it than simply removing the screw?

DON'T TAKE THE PEEP SIGHT OFF!!!!!!
Or, if you do, keep it safe for the next guy.

It swings out of the way of you don't want to use it, no need to remove it.

Why both sights? Because Mossberg thought people would like the ability to snap shoot using the barrel mounted sights, but then, if they had time, or were shooting targets for groups, they could swing in and use the aperture sight to get more accuracy.
Same reason several of the OEM front sights have different blades, some for targets, some for game.

Beautiful rifle, BTW, FAR nicer looking than mine.

 

First off your S107 has been heavily modified.

Mossberg was the only one to offer all three sights. But to answer your question, your front sight has 4 different post, 2 are shorter than the other 2, you could set you barrel sight to the shorter set and the peep could be set using the two taller ones. So you had the best of both options.

The S107 in it's original form could be lowered and not interfere with the peep. But a lot of shooters still found the barrel sight distracting. So they would remove them and most of the time they would get lost.

bone... If that's not an understatement, I don't know what is....😁

 

So you’re saying I’m not alone in putting small parts in a ziplock, labeling them, then forgetting the smart location I stored the ziplock?

 

Here are some pictures of what you rifle came with originally. Seems you front sight was modified as well.

Front sight was a S101, only thing that makes this sight a S106 is the dovetail adaptor. Same sight just an added part.

And this is an original S107

 

Sounds like the simplest solution to my problem is removing the rear sight, keeping it safely lost, then enjoying the unobstructed view between the receiver sight and the incorrect front sight. Sound good? Should I apply heat to the rear sight screw on the barrel before I attempt to remove it?

 

The screws should come out fairly easy. For what it would cost to replace the S107, I would say yes, just remove it. Then find some 8-40tpi plug screws to keep the trash out of the holes. Your modified front sight will work just fine with the peep sight.

 

Yes, the forward screw for the leaf came out easily. The screw underneath that holds the cradle is another story. It looks modified, as though it’s the wrong screw - the head is rounded over to match the barrel profile and it’s in the white. I may need to use something other than a screwdriver. I’ll load pics when I get home.

 

Bag it, label it (perhaps with a note) and always hang the bag on the rifle between uses.

 

Because "More Gun for the Money," that's why.

 

So I'm out if luck for finding a elevator for me S-107 rear sight?

 

You are aware that the rear peep swivels to the rear so you have a clear view of the rear barrel sight?
As to using the peep it is ok if you catch a little view of the rear barrel sight, ignore it, concentrate on the front sight and let your eye 'center it' in the peep aperture.
Have you just been shouldering and looking or actually shot it? it may be that once you dial in the peep elevation for your preferred distance that you will be looking over the rear barrel sight.
If not, the cheapest and easiest solution is putting on a taller front sight. They are readily available with the nominal 3/8" dovetail in sporting bead and target types, particularly the series of Lyman 17A.
