Specifics of the Weapon
The AR-15 rifle is a magazine fed, gas
operated, semi-automatic, shoulder-held weapon.
This weapon is chambered for a .223 caliber or (5.56 millimeter).
Nomenclature
First thing you need to know is a little about the nomenclature of the AR-15.
Listed are pictures of a few:
Stock: Made of high impact plastic and contains a
recoil reducing buffer assembly.
Barrel: The route in which the bullet travels.
Charging
Handle: Manually moves bolt
assembly to the rear during manual operation.
Rear
Sight and Windage Drum: Houses rear sight window.
Front
Sight Assembly: Houses the front
sight post.
Magazine
Well: Houses the magazine.
Magazine
Release Button: Releases the
lock that allows the removal of the magazine.
Magazine: Houses the rounds.
Trigger: Fires one round for each time squeezed.
Pistol Grip: Allows for secure handling of the weapon.
Ejection
Port: Fired brass is ejected
from the weapon here.
Selector Lever: Two positions, "safe" and
"fire."
Bolt
Catch/Bolt Release: Pushing on
the top (bolt release) releases the bolt.
Pushing in and holding the bottom (bolt catch) locks the bolt to the
rear.
Forward
Assist Assembly: Only on the
AR-15 A-2 model. Pushing in seats the
bolt all the way forward, if not completely closed.
Fundamentals
of Rifle Marksmanship
Marksmanship
Fundamentals: You the shooter
must understand the four key fundamentals, steady position, proper aiming,
breathing, and trigger squeeze, before you are ready to fire the weapon. You must
be able to establish a steady position that allows observation of the target.
You must aim the rifle at the target by aligning the sights, and you must fire
the rifle without disturbing this alignment by improper breathing or during the
trigger squeeze.
The skills needed to accomplish these are known as rifle marksmanship
fundamentals.
Steady Stance
When you the shooter approach the firing line,
you should find a comfortable, steady firing position in order to hit your
target consistently. Each shooter only has limited time on the firing line. You the shooter are the best judge as to the quality
of your position. If you can hold the front sight post steady through the trigger pull, you have a good position. To find a steady position elements are as
followed:
Body
position: The feet should be at
least shoulder width apart, and on an approximate 90 degree angle to the firing
line.
Non-firing
handgrip: The rifle hand guard
should rest on the heel of the hand in the V formed by the thumb and fingers.
The grip of the non-firing hand is light, and slight rearward pressure is
exerted. (The non-firing hand may also be wrapped around the magazine)
Rifle
butt position: The butt of the
stock is placed in the pocket of the firing shoulder. This reduces the effects
of recoil and helps to ensure a steady position.
Firing
handgrip: The firing hand grasps
the pistol grip so that it fits the V formed by the thumb and forefinger. The
forefinger is placed on the trigger so that the lay of the rifle is not
disturbed when the trigger is squeezed. The remaining three fingers exert a
slight rearward pressure to ensure the butt of the stock remains in the pocket
of the shoulder, minimizing the effects of recoil.
Firing
elbow placement: The location of
the firing elbow is important to providing balance. Placement should allow
shoulders to remain level while locking the stock in position.
Non-firing
elbow: The non-firing elbow is
positioned firmly under the rifle to allow for a comfortable and stable position,
allowing for equal movement to the left or right (wobble).
Stock
weld: The stock weld should
provide for a natural line of sight through the center of the rear sight
aperture to the front sight post and to the target. Your neck should be
relaxed, allowing your cheek to fall naturally onto the stock. You
should bring the stock up to your eye and not your eye down to the stock.
Natural
point of aim: When you first
assume your firing position, you must orient your rifle in the general
direction of your target. You need to adjust your body to bring the rifle and
sights exactly in line with the desired aiming point. When using proper support
and consistent stock weld placement, you should have your rifle and sight
aligned naturally on your target. When this correct body-rifle-target alignment
is achieved, the front sight post will stay on target. Adjusting to this point
is done by moving your back foot. (Adjust
your feet and body). You should adjust your natural point of aim to the
center of the expected target exposure area. Do not use upper body muscles to
adjust as they will relax and your alignment will change.
Aiming
Focusing on the front sight post is a vital skill
you must acquire during practice. You must align the rifle with the target in
exactly the same way for each firing exercise. Alignment of the rifle with the
target is critical. It involves placing the tip of the front sight post in the
center of the rear sight aperture. The weapon should be held with the front and
rear sight in an exact vertical position.
Do not "cant" the weapon.
Canting or tilting the weapon will result in the bullet striking off of
the aiming point. Aiming elements are as follows:
Sight
Alignment: When the sights are
properly aligned, the top center of the front sight post is exactly in the
center of the rear sight aperture. If an
imaginary horizontal line were drawn through the rear sight aperture, the top
of the front sight post would touch this line.
If an imaginary vertical line were drawn through the center of the rear
sight aperture, the line would bisect the front sight post. The shooter assures that he/she has proper
sight alignment by concentrating his/her attention and focusing the eye on the
front sight post. This will cause the
front sight to be sharp and clear and cause the rear sight aperture to be
fuzzy. Improperly aligned sights are the most common reason for bad hits or
misses.
Sight
Picture: Once you can correctly
align your sights, you can obtain a sight picture. A correct sight picture has
the following: target, front sight post, and rear sight aperture. The sight
picture includes two basic elements: sight alignment and sight placement. The
front sight, not the target or rear sight is the point of focus for the eye. As
such, the front sight will be sharp and distinct in outline.
Aiming
point: The aiming point is the
point on the target where the sights of the weapon are brought to bear. In
aiming the weapon, the shooter is concerned with correctly aligning the sights
of the rifle on the target in order for the bullet to hit the point of
aim. To do this, the shooter must have
the rear sight, the front sight, and the aiming point in proper relation to
each other. Due to the weapon's
location on one side of the body, the shooter will not be able to aim the
weapon using both eyes. The eye that is
on the side of the body as the weapon, is the
eye that must be used to align the sights.
If a shooter's dominant eye is on the same side of the body as the
weapon this presents no problem; however, sometimes the dominant eye is on the
opposite side. If this is the case, then
the shooter should move the weapon to the same side as the dominant eye. If a
shooter does not know which eye is the dominant eye, he/she can determine the
location of the dominant eye using the following exercise:
With both eyes open, extend one hand to arm's
length in front you and point at a specific spot with the index finger. While continuing to point at the spot, close
one eye. If your finger remains pointed
at the exact spot, then the eye that is open is the dominant eye. If your finger moved off of the exact spot,
then the eye that is closed is the dominant eye. Your eye can only focus on one thing at a time.
Breath control is another
fundamental, which is far more critical in target shooting than combat
shooting. Without oxygen, several interesting effects set in on the body, which
includes blurring of the vision, involuntary muscle tremors and eventually
unconsciousness. To obtain accuracy, you the shooter must learn to pause your
breathing at any given time during the breathing cycle. This must be done while
aiming and squeezing the trigger. To pause your breathing properly, you must
take a breath, let it out, then inhale normally, let a little out until comfortable,
pause your breathing and then fire. Do
not hold your breath more than 10 seconds before shooting. This may tense
your muscles and blur your vision. If you do not shoot during this breathing
period, take another breath and repeat the procedure. The shot must be fired
before you feel any discomfort from not breathing.
Trigger Control
Trigger
squeeze: A novice shooter can
learn to place the rifle in a steady position and to correctly aim at the
target if they follow the basic principles. If the trigger is not properly
squeezed, the rifle will be misaligned with the target at the moment of
discharge.
Rifle
movement: Trigger squeeze is
important for two reasons: First, any sudden movement of the finger on the
trigger can disturb the lay of the rifle and cause the shot to miss the target.
Second, the precise instant of firing, should be a surprise to you. Your
natural reflex to compensate for the noise and slight recoil in the shoulder
can cause you to miss the target.
Trigger
finger: The trigger finger (index finger on the firing hand) is
placed on the trigger between the first joint and the tip of the finger (not the extreme end) and adjusted
depending on hand size, grip, and so on. The proper trigger
squeeze should start with slight pressure on the trigger during the initial
aiming process. You should apply more pressure once the front sight post is
steady on the target and you are pausing your breathing. You will experience a
greater wobble area from the standing position. Wobble area is the movement of
the front sight around the aiming point when the rifle is in the steadiest
position. This is caused by blood flowing through your system. If the front
sight strays from the target during the firing process, pressure on the trigger
should be held constant and resumed as soon as sighting is corrected. You should never try to quickly squeeze the
trigger while the sight is on the target. The best firing performance
results when the trigger is squeezed continuously and the rifle is fired
without disturbing its lay.
The basic fundamentals are the foundation for
good rifle shooting. In order for a
shooter to improve his/her abilities, these fundamentals must be followed each
time he/she fires the weapon. As with
any weapon, safety should be the number one consideration when carrying,
loading, unloading, or firing the rifle. Practice makes perfect so practice often.

























Thanks for this wonderful teaching.
