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.
I have had several. Two 38-55's, two .32 Specials, a 30-30. All of them had the capacity for adjusting the sights (drift left-right, "ladder" elevation), is not rocket science. What you posted: "...it's not [hitting] where I'm aiming...", as opposed to not grouping
indicates, not sighted in. "...not an easy operation...", indicates ignorance (we can fix that here). The rest of if indicates immaturity (that will take time)
