After sighting it in, accuracy with mil spec aperture sights was acceptable. A scope would likely cut the group size in half. A trigger job might cut it in half again, as the factory trigger felt like it was pushing ten pounds.
Sight was set to the 200 yard aperture (the 100 yard sight has a V-notch, so offering less precision, I didn't use it), therefore the group being a bit high was correct. Ammo was British military surplus 7.62 NATO.
