I go through one way to zero your AK-74 (and variant) rifle. I suggest either doing it the way I do in the video or just using the battle setting and zeroing point of aim=point of impact.
Basic front sight adjustments:
If you want to move the group to the right-----move the front sight left. If you want to move the group to the left----move the front sight right. If you want to lower your group, raise the front sight (counter clockwise) If you want to raise your group, lower the front sight (clockwise)
Ballistics numbers of the 7N6 round:
Bullet weight - 3.42 grams (53gr) initial velocity, according to the manufacturer - 870 m / sec (2854 ft/s) Ballistic coefficient: 0.282
Below is some data taken from a 1980s Russin AK74 manual:
Velocity in ft/sec Distance in meters 0 = 2970 (note this is for the particular 5.45x39 round in use at the time) 100 = 2673 200 = 2340 300 = 2056 400 = 1792 500 = 1508 600 = 1310
