1. Place on fire, lock bolt to rear

2. Safety on

3. Return cocking handle forward

4. Raise cover and feed mechanism and visually inspect chamber, receiver and magazine well

5. Close cover, select fire, and ride the bolt gently forward using the cocking handle while pressing the trigger to rear

6. Weapon remains on fire (bolt forward, weapon on fire)

The weapon must always be CLEARED before disassembling.

ROLES OF THE AUTOMATIC RIFLE

• Support rifleman

• Engage intermediate distance targets

• Heavy volume of fire

• Assault weapon in close quarters or entry procedures

CHARACTERISTICSOF FIRE

• Trajectory

• Maximum ordinate

• Cone of fire

• Beaten zone

• Danger space

• Dead space

CHARACTERISTICSOF FIRE

• Trajectory--path of projectile

– Almost flat at 300 meters or less

– Beyond 300 meters, trajectory is curved and becomes greater as range increases

CHARACTERISTICSOF FIRE

• Maximum ordinate

– Highest point trajectory reaches from muzzle to target

– Occurs at 2/3 of distance between gun and target

CHARACTERISTICSOF FIRE

CHARACTERISTICSOF FIRE

• Cone of fire– Pattern formed by several rounds in a

burst, each round taking a slightly different trajectory

– Caused by vibration of the gun or variations in ammunition and atmospheric conditions

CHARACTERISTICSOF FIRE

• Beaten zone-area where cone of fire strikes the ground• Changes when range to target changes

– Uniformly sloping or level terrain, beaten zone is long and narrow

– Beaten zone becomes shorter and wider as range to target increases

– Terrain sloping down and away, beaten zone becomes longer

– Terrain rising, beaten zone becomes shorter– Terrain has no great effect on the width of the beaten

zone

CHARACTERISTICSOF FIRE

CHARACTERISTICS OF FIRE

• Danger space-space between gun and target where trajectory does not rise above 1.8 meters

• Fired over level terrain – Danger space to 700 meters

CHARACTERISTICSOF FIRE

• Dead space-area that can’t be seen or covered by gun position– Caused by depressions, rises,

obstructions, etc.– Must be covered by a different weapon

position or other type of weapon ie. M203

RANGEDETERMINATION

• Position disclosure

• Required for reporting adjustment of fire

1. Prone position2. Right handed3. Feet spread, heels down4. Shoulder rest up

Grip• Right hand on grip• Left hand on cover• Weapon pulled into shoulder with

3rd and 4th fingers of the shooting hand

Aiming• Sight alignment

1. Front-sight blade centered in rear sight aperture

2. Top of front-sight blade even with center of rear sight aperture

Aiming• Sight Picture

1. Top of front sight on center base of target

2. Eye focus on front-sight

Trigger Manipulation• Pull trigger and release• Control rounds in burst

Windage• Turn sight full left• Count number of clicks while

turning windage knob full right• Back off half the number of clicks to

the left

Elevation• Turn sight full up• Count number of clicks while

turning sight full down• Back off half the number of clicks

up

Windage knob1 click = 6 in. at 300 meters
