Front sight adjustment on Mosin 91/30

[offthepaper]

How do you adjust the front site on a Mosin Nagant 91/30? I just recently recieved 1932 Tula with lamenated stock that is in very good condition, however the front sight is in need of adjustment as all my groupings are to the right of the point of aim @50-100 yds. It is visible to the eye that the sight blade is left of centerline of the barrel. Any info appreciated.

Is the bayonet extended? If not, try that before touching it.

You have to drift the sight. Use a brass or steel punch and tap the base of the site in the direction of the correction.

dispatch55126 is correct that you need a drift the sight by using a punch (preferably brass).

However I think if you wish to have your bullets go more left you need to drift your sights to the right, if you were looking at it from the standpoint that you were ready to shoot...

example

You are shooting to the right...
Lets say this is how you see your sight right now
...|.....
Then you want to move it to this way:
.....|...


If you think about it, if you were to move your sight to the left that would make you bullet actually go farther right than it is now.

you "chase" the round

meaning if the hole on the paper is left you want to push the front post left

 

[offthepaper]

Yes, I believe I want to move the front sight post to where the round is hitting. Is that correct?
And I should be able to tap the sight with a punch to zero it?

 

[Hoppy590]

yup, get a brass punch, a small hammer, and some patience.

How about for elevation?

Davo:
I've wondered that myself. Is the front sight post threaded, so as to allow the raising and lowering of the front sight post to compensate for longer or shorter distances?

 

[cracked butt]

No, you need to fabricate a taller front sight if its shooting high. If its shooting low, just raise the rear sight.

Brass punch and small hammer?

After I couldn't move the front sight on my 91/30 by tapping then pounding with a 1 pound ball peen hammer I went back and looked for a set screw. Then I moved on to a big steel punch and 5 pound sledge. That's part of the appeal of these rifles. They're built to stand the abuse of peasants like me.

To build up the front sight post if you're shooting high -

Get yourself a spare front sight post.
Clean it REALLY well. Drill a few small holes into the top of it.
Build it up with some JB Weld. Force JB Weld into the holes to make it hold better.
File the JB Weld to shape it. File as necessary to to adjust elevation.
Paint it with flat black paint or hit it with some Sight Black.

If you have a small welder, that would be better than JB Weld.

Use a brass or steel punch and tap the base of the site in the direction of the correction.

I always thought you moved the front site in the opposite direction of how you wanted to change the point of impact, and the rear sight in the same direction.

A quick fix to the elevation adjustment (if your rear sight elevation is all the way down and you still shoot high) is to wrap the front sight in electrical tape to make it taller. I did this with mine and it stayed on for over a year before I took it off......beware...it will be gooey (although it won't change shape).
