Stuck up here (rural Missouri) and got Dixie on my
With my rear sight as low as it will go and seeing the front post as deep in the notch of the rear sight as I can, my mosin shoots 5" above point of aim at 25 yds. and 20" above point of aim at 100 yds. Very frustrating. Windage is spot on. Any ideas?

I love shooting the old thing but would like to not have to hold under that much>
 
One thing ou can do is remove the front sight and remove the pin, drill out the hole so that it goes all the way thru and drive in a round steel pin then tap it down more to raise point of aim or pull it up to lower it.
 
What ammunition?

In looong barrelled rifles slower loads tend to print higher than faster ones if the disparity is enough

If need be its super easy to adjust/extend an sks,mosin,AK sight post

Hello,

They are made to be fire with the bayonet affixed. This is how they were sighted in.

The Mosin-Nagant will shoot high and perhaps a bit right with the bayonet not mounted.

Please feel free to visit my website, http://smith-sights.com . You can purchase an adjustable sight there, or you can make your own taller post by using a nail from the hardware store.

Either way, you're welcome to look around. I've written a lot of articles you may find very helpful.

Regards,

Josh
 
A Mosin I used to own shot high. I cut a piece off of a brass key which was about the same thickness as the Mosin's front sight. Epoxied it to the top of the front sight and then filed some off to get it to shoot on target at 100 yards. The fix lasted for over 10 yrs and was on the riflel when I sold it.
 
This is what I have gathered from information found from the internet. Take it with a grain of salt.

Russian troops were instructed to use the belt buckle of an enemy target for their point of aim. When zeroing at 100 meters they would set the rear sight on 3. The mean point of impact of a group fired would then be 17 centimeters (6 45/64") above the point of aim. For acceptance... all rounds must place within a circle of 15 cm (5 29/32") diameter circle. No round could be more than 5 cm (1 31/32") from the mean point of impact.

For the 91/30 to be concidered for sniper acceptance the rifle must group within a circle of 8 centimeters with no round being more that 3 centimeteres from the MPI using open sights.

It would appear that your rifle is shooting high and outside of the acceptance range. Easiest solution would be to replace or modify and repair the front sight.

Just my understanding, others will vary.

Loosenock, they were sighted in with the bayonet attached.

A Mosin-Nagant without the bayonet affixed will shoot high and usually a bit right.

The way I fixed mine was to remove metal from under the rear sight and the sight ramp. I used the Smith Sight to tweak it. The problem I had was if I raised the front sight enough to correct the elevation the sight picture was restricted too much.
 
On mine I've both filed off a bit of metal from the movable heel block on the rear sight and at the same time made a roughly .060 longer pin for the front sight. I can now get it to shoot to POA at 100 with a notch or two from the lowest rear setting.

It was either that or paint belt buckles on my targets about a foot below the bull.... :D
 
It's also a battle rifle. Not intended to shoot at target 25 yards away, usually 10 times that distance or more. But the wire insulation on the front post is a very cheap and effective solution. Adjustable too.
 
+1, the insulation route is the cheapest, most cost-effective method for adjusting the front sight. It really works well, too.
 
I just used a ....ahem...well used, swizel stick (mixed drink stir ) from a well deserverved cocktail I enjoyed and cut it to size and slipped it over the front sight post. Quick and easy. Try to get a red swizel and cut the top to a point for a pretty nice front sight post. Once I had it exactly how I wanted it, I just put the tinest dab of Elmers glue on the front post and slipped it on. Holds it in place but can easily get it off if you want.
 
Just buy a new one. You would spend that much getting new sights for it or having any work done to it.
 
offthepaper; awesome. just awesome. nominate for post of the year. most best, easy suggestion ever. and yes, at 50 yds, mine is 3" high and 3" right. now after reading this thread, i know why.

my nephew that is a really good shot, has his MN hitting a gong target at 400 yds. got it adjusted with a pair of pliars.

Actually BCRider I never really had a desire to get one until I joined THR maybe I'll get myself one as a belated birthday gift to myself seeing as the only thing I got for my birthday was married.
 
I think offthepaper is right on the money if you wanted to fix it, personally I would just remember to compensate.
 
I filed down on the bottom of the rear sight on mine. Took a while and quite a bit of ammo but it wasn't too hard. Just a lot of trial and error

I have an 8mm Mauser that had the same problem. It had a 300 meter zero and that made it tough to shoot at 100-200 yards. I made a taller front sight out of a shaft key and it worked fine. Later, I found extended front sights at Brownell's for very reasonable cost.

The same could be true for the Mosin rifles.

Hello,

I have one of those Brownell's sights on my Gewehr 88 Commission Rifle. After getting it shooting right on, I sharpened it a bit with a carbide knife sharpener. Nice and precise now, but not pyramid-shaped like the original.

There are one or two people who sell new posts for the Mosin. The problem with these posts are 1) They're more expensive than they need to be; a 2mm or 3/32 nail works well, and 2) Many (most) times the stock posts are soldered in and simply won't come out with a hammer and punch.

That's why I do what I do.

Not an advertisement at all; just hard fact about these sights. They were made to be indestructible, and danged near are!

I keep hearing that the rifle was sighted in with the bayonet affixed to the front but has anyone
actually tried to shoot their MN with the bayo to see if this statement is actually true?
