M39 sight knowledge

[Danus ex]

It had been a while since I shot the M39, so I took it out today and quickly remembered how much I like it. While it's ridiculously easy to be precise with this rifle, being accurate is another thing entirely. Mine shoots about a foot high at 100 meters using Bulgarian heavy ball. At 150m, it's around 6 inches high. I did not take the rifle out to 200m today.

Are the M39's sights calibrated for a certain distance? I assume so, because I've read that the Finns had a number of different front sight heights available, and they must've given me a #82 front sight for some reason. At what distance is POI supposed to equal POA on an M39?

Milsurp rifles are often not calibrated correctly, even if you shoot the same surplus ammo that they were issued with. I'm not exactly sure why.

Folks say that they were calibrated for longer range battle zeros, but when a sight has 200m marked on it, that's where it should zero. (a 200m zero with 7.62x54R light ball is something like merely 2" high at 100 yards)

Luckily, for the M39 this is an easy fix. Tennessee Gun Parts has taller sights for M39s and a few other rifles. Get one, put it on your rifle and file it down carefully until the rifle zeros properly to its markings with your ammo.

M-39s were zeroed at 200m for a 6 o'clock hold on a (if I remember right) ten centimeter wide bullseye target.
