I have run across several Mosins that shoot too high at the lowest setting. This may be in line with the Russian think of aiming at the knees and hitting the upper body or just a poor pick of foresight. If the post is too short then you have no adjustment left. Finding a replacement can be a pain, so I worked out a simple and reversible solution.
Take a 1/8 x 1/2" aluminum pop rivet. Drill it out to 5/64" (that may vary depending on the brand. Clip off a part of the flange of the rivet on one side. Lift the rivet up through the hole on the sight guard and push it down over the post. It should be snug. I make them snug enough that they require a bit of a tap with a punch and hammer. But only a tap.
A drop of blue loctite in the rivet before forcing it on will bond it well.
Paint it black with a felt marker and zero in at 50 meters. File down the post to raise the mpi. A little goes a long way.
!/2" rivet will give you way more than you need.
The great thing is that you have not altered the rifle and you would have to look hard to notice it.
I also file the sides of the new sleeve down at a bit of a bevel once proper elevation is met.
