Yes, Blakey is right (boy, you got to read every word or this stuff gets by you...):
1. Assume what you believe to be a natural body position with a firm grip on your weapon and with sights lined up on the target.
2. Close your eyes and slightly relax your position (aka relax your hold out of the aiming position but dont move your body)
3. Without opening your eyes, take up your body position again with a firm grip on your weapon and with sights lined up on the target.
4. Open your eyes. If you are not lined up on the target, either left-right or up-down, re-align your body position.
5. Repeat as required, although with expereience you should be lined up after your first alignment test.
For those in close-quarters combat conditions, the above guideline is not applicable;
1. Keep both eyes open and watch where your rounds splash; adjust as needed using the forefinger along the forestock as a guide.
