13 are three elements of a good shooting position that apply when using a loop sling:
14 (1) Bone Support. The body's skeletal structure provides a stable foundation to support the
15 rifle's weight. A weak shooting position will not withstand the repeated recoil of a rifle when
16 firing at the sustained rate or buffeting from wind. To attain a correct shooting position, the
17 bones of the body must support as much of the rifle's weight as possible. Proper use of the
18 sling provides additional support.
19 (a) The weight of the weapon should be supported by bone rather than muscle because
20 muscles fatigue whereas bones do not.
21 (b) Establish a strong foundation for the rifle by utilizing bone support. This will enable
22 the Marine to relax as much as possible while minimizing the movement of the weapon
23 due to muscle tension.
24 (2) Muscular Relaxation. Once bone support is achieved, muscles are relaxed. Muscular
25 relaxation helps to hold the rifle steady and increase the accuracy of your aim. Muscular
26 relaxation also permits the use of maximum bone support to create a minimum arc of
27 movement and consistency in resistance to recoil. There is no way to achieve muscular
28 relaxation without bone support. During the shooting process, the muscles of the body must
29 be relaxed as much as possible. Muscles that are tense will cause excessive movement of the
30 rifle, disturbing the aim. When proper bone support and muscular relaxation are achieved, the
31 rifle will settle onto your aiming point, making it possible to apply trigger control and deliver a
32 well-aimed shot.
33 (3) Natural Point of Aim. The point at which the rifle sights settle when bone support and
34 muscular relaxation are achieved is called the natural point of aim.
1 (a) Since the rifle becomes an extension of the body, it may be necessary to adjust the
2 position of the body until the rifle sights settle naturally on the desired aiming point on the
4 (b) When in a shooting position with proper sight alignment, the position of the tip of the
5 front sight post will indicate the natural point of aim. When completely relaxed, the tip of
6 the front sight post should rest on the desired aiming point.
7 (c) One method of checking for natural point of aim is to aim in on your target, close
8 your eyes, take a couple of breaths, and relax as much as possible. When you open your
9 eyes, the tip of the front sight post should be positioned on the desired aiming point while
11 (d) For each shooting position, specific adjustments will cause your rifle sights to settle
12 center mass, achieving a natural point of aim.
13 • In all positions, natural point of aim can be adjusted by:
14 • Varying the placement of the left hand in relation to the handguards.
15 • Moving the left hand forward on the handguards lowers the muzzle of the
16 weapon, causing the sights to settle lower on the target.
17 • Moving the left hand back on the handguards raises the muzzle of the
18 weapon, causing the sights to settle higher on the target.
19 • Varying the placement of the stock in the shoulder.
20 • Moving the stock higher in the shoulder lowers the muzzle of the weapon,
21 causing the sights to settle lower on the target.
22 • Moving the stock lower in the shoulder raises the muzzle of the weapon,
23 causing the sights to settle higher on the target.
25 • Natural point of aim can be adjusted right or left by adjusting body alignment
26 in relation to the target.
28 • In the prone position, if the natural point of aim is above or below the desired
29 aiming point, move your body slightly forward or back using your left elbow as a
30 pivot and by digging your toes in.
31 • Pushing your body forward causes the sights to settle lower on the target.
32 • Pulling your body backward causes the sights to settle higher on the target.
• In the kneeling and sitting positions, natural point of aim can be adjusted by varying the placement of the left elbow on the knee.
• Moving the left elbow forward on the knee lowers the muzzle of the weapon, causing the sights to settle lower on the target.
• Moving the left hand back on the knee raises the muzzle of the weapon, causing the sights to settle higher on the target.
