Yes. The rear sight blade on a Mosin-Nagant rifle is in metric increments. Russia and the Soviet Union never used the Imperial system, nor did any country which manufactured the Mosin-Nagant under license from the Soviet Union (Mosin-Nagant rifles were manufactured in the US from 1915 - 1917 under contract from the Russian Empire prior to the Bolshevik Revolution, but those also had sights measured in metric intervals. Rifles were also manufactured for the Russian Empire in France, as well).
Either the front sight will need to be raised, the rear sight lowered, or you will need to aim lower. Most military rifles have a minimum zero distance around 200 yards. If you are shooting at a closer distance, expect that the strike of the bullet will be other than point of aim.
,The Mosin-Nagant was normally sighted with the bayonet affixed. This will change the point of impact.As well, the sights were regulated to hit the torso of an enemy soldier at 0 to 350 meters or so. It will therefore hit about 6" to 12" high at 100 meters/yards.Windage may be adjusted by drifting the front sight in its dovetail. If it is shooting left, drift it left. If it is shooting to the right, drift it right.To bring the point of impact down lower, you must replace the pin. First, drift the sight out of its dovetail and secure it so that the pin may be driven out of the bottom.Insert a punch through the hole in the top of the sight hood, and smack smartly with a hammer. The pin will come out.The sight pin may be replaced by a nail of appropriate size. Install, and test fire. Trim the sight pin to length.(I build custom sights for the Mosin-Nagant, and before shipping them I set the pin height to 0.325". I find this works for the vast majority of Mosin-Nagant 91/30 rifles).I hope this helps you.Regards,Josh SmithSmith-Sights.com
Pre-1930's are measured in arshini ( 1 arshin = 71.12cm OR about 28 inches) Post-1930's are measured in meters
1. Remove the screw to the rear of the front sight ramp.2. Remove the "blade" from the front sight ramp.3. Remove the screw from the front of the front sight ramp (which was formerly seated under the "blade").
It depends on the model you have. With the M44, your bayonet has to be extened to achieve maximum accuracy, it dampens barrel vibrations and the Russians sighted them in with the bayonets out, so shooting with it retracted will cause it to shoot off center by a few inches. If you are trying to adjust windage ( and this goes for all rifles), you need to drift the front sight over to the left or the right, depending on how bad your shots are off center. Example, if your shots are hitting 4 inches to the left, move your front sight over to the left, which causes your body to move the rifle more to the right to line up the sight picture, which also brings your shots more right. Its easy. It shoots left, adjust sight to the left, shoots right, move front sight to the right. This is opposite on pistols where the windage adjustment is actually the rear sight rather the front sight. Moving the front sight for windage by as much as 1-2mm is enough to chance the shot placement by 2 or 3 inches at about 100 yards or meters. If your mosin is shooting too high, aim a few inches lower, doesn't take much. I find if I aim right at the bottom line of the bullseye my shots will be dead center, however if I aim for the center of the bullseye the shots place about 2 inches too high. Before you go messing with the front sight, have several others try out the rifle. If you are jerking the trigger (its easy to do even if you "think" you aren't doing it), by the time the trigger releases and fires the weapon you have flinched, causing you to move the barrel off target.

I only own 2 mosin variants, but my knowledge of them is very very high. From simple problems they sometimes have, to their history, or safety concerns. -tom

There are two screws securing the ramp to the barrel. One screw is quite obvious at the rear of the ramp. The other screw is under the front sight blade. Remove the front sight blade and you will be able to remove the mounting screw.
Two methods- one uses a long eye relief scope, and the mount is ttached to the ear sight base- known as a "Scout" mount. The other method uses a scope mount that is attached by drilling and tapping the reciever- but the bolt handle must be modified to a bent shape to clear the scope.
That is a difficult rifle to scope, and I have not seen a reciever mount other than the PU type. Some folks have used a long eye relief scope, and mounted it to the rear sight base. Sorry-
Let a gunsmith do it.
Only 1 screw is visible, there are 2. Remove front sight hood, drive dove tail blade out from left to right. The other screw is visible now. Remove both screws and the ramp comes off.
