The Finns know how to set them up. It came with a shimmed stock, and is the most accurate of the group.
The M38 does 2 MOA with hunting ammo and the 4x scout scope. The Finn beats that, preferring the Yugo surplus over new ammo, with 1 MOA, if I do my part. Only thing is it shoots 12” high at 100 yds and 6” high at 200 yds. I’ll need a longer range if I’m ever going to move the leaf sights above “zero”.
The sights were supposedly calibrated for the bayonet being attached. Or so I heard on the interwebs.

These guys sell peep sights for a number of surplus rifles, including Mosins. I’ve got a set on one of mine, front and rear peeps, and I absolutely love them.
