I was having some issues the other day when sighting in my red dot sight. I am new at this and have never had to sight in optics before. Please help when within 15 yards she is dead on but as it goes out farther I can see where I am hitting. I almost feel like It is not lining up. If I move it more forward toward the barrell will that help me get in the right range or is my sight just garbage or am I just retarded? thanks guys.
