That'd be about average. Its a small light barrel. Even the new series, touted as somewhat more accurate, ain't really bench rest guns. Combine that with run of the mill 7.62 ammo and 3 to 4 inches.
Look at it this way, you own a small, light, tight carbine that is dead reliable and actually looks good (compared to the horrifically ugly in any form AK/SKSs and the ARs which look fine till they get hung with 14 liner feet of pickaninny rail/flashlights/grips/spring loaded bayonet launchers and GPS range finding electro-dot laser sights with Domino's pizza ordering capability)....carries well and won't be breaking down every third shot because it only works with 4 oz of gun frog pee grease on the bolt receiver group (ala AR!).
3 to 4 inches....that's a dead deer every shot out past 150 yards. That's rolled soda cans all day long in off hand plinking practice. That's a reliable and reasonably accurate starting point.
Practice and good ammo and perhaps a scope might tighten it up a bit.
Beware of the man with one gun, even if it "only" shoots 3" groups, because he likely knows how to use it.
Luck.
