movement. This is caused by the firer anticipating the shot or using improper trigger squeeze. Proper trigger squeeze results in no movement when the hammer falls. If the firer knows when the hammer is going to fall, movement can often be observed at that moment.

Dime (Washer) Exercise. This dry-fire technique is used to teach or evaluate the skill of trigger squeeze and is effective when conducted from an unsupported position. When using the M16A1 rifle for this exercise, the soldier must cock the weapon, assume an unsupported firing position, and aim at the target. An assistant places a dime (washer) on the rifle's barrel between the flash suppressor and front sight post assembly. The soldier then tries to squeeze the trigger naturally without causing the dime (washer) to fall off. Several repetitions of this exercise must be conducted to determine if the soldier has problems with trigger squeeze.

If the dime (washer) is allowed to touch the sight assembly or flash suppressor, it may fall off due to the jolt of the hammer. Also, the strength of the hammer spring on some rifles can make this a difficult exercise to perform. Instructors should allow soldiers to use another rifle when the one they are using is defective or needs repair.

When using the M16A2 rifle, the dime (washer) exercise is conducted the same cxccpt that a locally fabricated dcvicc must be attached to the weapon. A piece of 3/4-inch bonding material is folded into a clothes-pin shape and inserted into the compensator of the weapon so that the dime (washer) can be placed on top of it.

NOTE: The Weaponeer is discussed in Section II.
