Nice thought, but since they are fixed sights, it's not an easy operation. Have you ever looked at a 94? I know how to zero a firearm. Wouldn't have made it very far as a Paratrooper if I didn't.
It is a pretty easy operation really. The elevation is simple and self explanatory when you examine the rear sight. Windage is adjusted by drifting the rear sight. Use a brass rod and a hammer. Right to move the group right, and left to adjust to the left.
Your sights are off, that's why you are not hitting where you are aiming. Adjust the sights. The real issue is whether you are getting an acceptable group.
