Default Loose Front Sight on 1903 Springfield

The front sight on my '03 is loose, I went to tighten it up but the set screw does not tighten the sight. The set screw has a post (unthreaded) section that fits into a recess in the front sight itself. The dovetail also seems to be tapered so as I drift it to the left it gets tighter in the dovetail, but where it tightens up is quite a bit offset to the left. I cannot insert the dovetail from the left to the right, only from the right to the left.


Anybody have any advice for me?

The sight has "Marble" stamped on one side and "Sheard #11" stamped on the other side. Here are some pics of it.

It's typical for the dovetails to be tapered. Not sure I'm understanding the problem with the set screw. It looks like your sight blade has been hammered on a bit. You might need a new one.

Loc-tite might help.

Or pin it in place.

Well yes, it is an old rifle and it has been around the block a few times. I'm not sure how this set screw is supposed to work. It would make sense if the tip of the screw was tapered to lock things in place rather than it being straight like it is. Rather than replacing it I would prefer to fix the one I have. I am thinking of pinning it with a taper pin in place of the set screw.

One simple thing to do is lightly tap on the dovetail projections. on the top photo the lips on the barrel part can be tapped down slightly. very gentle it won't take much and should be invisible when the front sight is put back. tap and check until you are happy with it.

That's what I was thinking, that and maybe making another set screw that is tapered. That would be a bit difficult though. Or maybe not. Maybe I could make a tapered pin, ream out the pin hole in a matching taper and then stake the pin in place.

You might try lowes/home depot as they often have a variety of set screws.

I have a metric crap-load of set screws, probably more than Lowes or Home Depot but nothing that would work. I checked.

Dang what about finding the dimensions and chucking something up in the lathe. I know it's not easy but it may be worth the shot?
