1. Ensure the soldier is proficient with the M68
2. Ensure with the M16A1/A2 that the M68 does not have the half moon spacer installed
3. Ensure with the M4, M16A4, and MWS that the M68 has the half moon spacer installed
4. Ensure the proper offset is used during bore sighting procedures
5. Confirm 10-meter bore sight with 25 meter zero
6. Ensure rail grabber is retightened after initial 3 rounds are fired
7. Ensure soldier has the M68 dot set for best sight picture.
8. Ensure that the soldier applies the marksmanship fundamentals
9. Ensure the soldier zeros and qualifies with the same sight picture (1 or 2 eye method)
10. Ensure soldier zeros on the M16A2 25 meter zero target
11. Ensure designated impact zone is 1.4 centimeters down from center mass of the 300-meter
12. silhouette on the 25-meter zero target.
The M68 is zeroed to the same standards as with iron sights, Rounds must impact in the 4x4 square designated impact zone. Soldier achieves the same practice qualification and qualification standards as with day record
Soldiers must qualify on their assigned weapons during daylight conditions as outlined in this manual. The integrated act of firing with the M68 is identical to the iron sights except for the change in sight picture. The M68 training strategy is the same as the iron sight training strategy.
b. Conduct of Training. All procedures for the M68 are the same as with standard iron sights. The M68 equipment training should familiarize the soldier with the proper operation and characteristics of the M68 in accordance with TM 9-1240-413-12&P.
(1) Modified Fundamentals. The fundamentals of marksmanship are modified asfollows:
a) Steady Position. Placing the cheek on the stock weld to get a good sight picture after the M68 is zeroed at 25 meters is no longer necessary. The M68’s reflexive sight allows the soldier to fire the weapon with his cheek at a comfortable position; however, the soldier must zero with the same cheek position he will fire with because the parallax free is only effective beyond 50 meters.
(b) Aiming. The preferred method of aiming using the M68 is to keep both eyes open, which allows a much greater field of view and makes scanning for targets much easier. However, getting accustomed to the two-eyes-open method takes practice. The soldier must keep the rifle and M68 in a vertical alignment each time he fires.
Two-eyes-open method (preferred).
Position the head so that one eye can focus on the red dot and the other eye can scan downrange. Place the red dot on the center of mass of the target and engage.
With the nonfiring eye closed, look through the M68 to
ensure that the red dot can be seen clearly. Place the red dot on the center of
mass of the target and engage. If the soldier zeros his weapon using the
one-eye-open method, he must engage targets using this method for zero

(d) Trigger Squeeze. This fundamental does not change.
