What don't I know about my new Mosin Nagant?

[someguy2800]

I have also seen it in auto parts stores.
FYI; some folks use a large roll pin, as it is sturdier than shrink tubing

I was thinking of drilling it out and putting a .080 roll pin in its place so I can adjust it up or down as needed and just use the roll pin as the sight post. Otherwise I might see if I can use a spare die decapping pin

some just slip the roll pin over the post - easy to undo that way

To me a gun that shoots 6" high at 50 IS broken!

Ahhh, Many of the old milsurps had a minimum setting on the rear sight setting of 2-300 meters. So MOST of them shoot very hight at 100yds or less. Thats the way they are. Simplest thing is to raise the front sight. Easiest way is to slip heat shrink or a "spray straw" over the front post.

I don't really want a reversible solution, or something that can fall off. I'd rather just fix it for good and be done with it. On this one the rear sight is marked 100 meters as the lowest increment so I will adjust the front post to be on at that distance. If the 200 meter increment is then correct it will be icing on the cake. My nearsighted eyes make any distance past that irrelevant for iron sights shooting but maybe some day I'll try it farther out too.

Just a few thoughts from me, I have a 1903a3 with the WWII army sight hood and the typical army narrow blade (not the taller USMC hood nor wider sight)--if the sight post is tall enough in the Mosin with the hood, from your angle it can get a bit harder to distinguish with poor eyesight from the hood versus the front sight. In less than perfect light, I can have that problem with the 03a3.

I share your near sightedness and also have astigmatism and those old narrow sights are hard enough to distinguish at distance already. Coloring your front sight post differently can make a difference--I use cheap horribly colored hot pinks/oranges/yellow finger nail polish. Another thing that works until dirty is typewriter whiteout. Both methods are easily reversible.

Try the temp fix with something black first before drilling to see if your sight picture is ok--then have at it if you wish. You will also have to set the height by trial and error via live firing and it is easier to fix a soda straw or shrink tubing cut too short than a new metal front sight pin. After you have the height set for your rifle via the temp pin addition, then you know what you need for the permanent metal one. I would drift the front sight off before drilling out the sight pin though as damaging the front sight dovetail is an expensive fix. It would be safer and easier to drill it out from the underside anyway.

Well that was easy. I knocked the sight out quick and examined it. It appeared that the original sight post went all the way down to the dovetail on the sight. I put it in the bench vise and stuck a punch down through the hole in the top of the sight hood and smacked it but it wouldn't budge so I drilled up through the bottom of it and it came right out.



Next I went in my tool drawer and found an allen wrench that was just larger than the hole. Driving a hex into a round hole makes a nice secure interference fit that can still be easily drifted in and out.



My first thought was spin it in a drill against the bench grinder to taper it down and make a fine target post.



I tried that on the gun but my poor eyes just couldn't see it so I cut a new piece and left it full width and drove it in place with a brass hammer



voila



This just about fill out the rear sight notch so the size is about right for me. I'll adjust up/down left/right as needed

yet another simple fix

You have an MO triple date. No one seems to know what that means but they are somewhat rare. Mine shoots tighter groops than my other Mosin Nagants. I don't know if that's luck of the draw or characteristic of the triple date rifles.
