LEARNING OBJECTIVES With the aid of references, identify the

characteristics and nomenclature of the ACOGscope.

Without references, demonstrate the propermounting of an ACOG to the weapon.

Without references, demonstrate the use of the

ACOG scopes Bullet Drop Compensated Reticle. Without references, conduct maintenance on an

ACOG scope. Demonstrate by scored live fire, marksmanship

up to 800meters using an M16A4/M4 MWS with an

ACOG scope during daylight hours. Demonstrate by scored live fire, marksmanship

up to 300 meters using an M16A4/M4 MWS withan ACOG scope during periods ofdarkness/reduced visibility.

INTRODUCTION TO THEACOG SCOPE

TA31F

TA31RCO


3/50

DESCRIPTION

The ACOG scope is a lightweight,rugged, four power optical scope.

Designed for the M4/M16A4, the ACOGprovides an auto ranging reticle forranges up to 800 meters.

Through the use of both fiber optic and

tritium the ACOG is dual illuminatedduring both day and night without theuse of batteries.

CHARACTERISTICS

4x magnification.

Weight = 15.3 ounces w/M1913 rail adaptor.

32mm objective lens.

Waterproof to depth of 66 feet w/adjustercaps on.

Eye relief 1.5 inches.

Field of view at 100 yds. = 36.8 feet

Adjustments (3 clicks = 1 inch @ 100m)


6/50

The TA31F ACOG does NOT have anocular laser protection. Do not use thescope unless you have proper eyeprotection (SPECS-3 laser goggles), orlasers are not in use, or risk mitigationmeasures are in effect.

Example, PEQ-2A in combat mode.

ACOG USE

Due to the use of tritium and fiber optic lightdevices the scope will allow the use of the BindonAiming Concept (BAC) of shooting with both eyesopen.

The ACOG can be used to scan an area. When a target is acquired, use the ranging reticle

(if time allows) to get an accurate range to thetarget.

Use the range aiming point on the bullet dropcompensator, and engage the target.

The scope can also be shot with holding only one

eye open. (Preferred method for farther targets.)


9/50

RANGING FEATURE The horizontal stadia lines represent

19 inches at the respective ranges.(between 400m & 800m they should fitthe average width of the frontal view

of a man shoulders). Range your target using the width of

the stadia lines. The outside legs ofthe Chevron equals 19 inches at

300m.


10/50

TARGET REFERENCE SYSTEM The TA31RCOM150 reticle includes a horizontal

graduated in 5 mil increments. The distance from the centerpost to the first mil-bar on

either sideis 10 mils. The horizontal mil-scale is primarily used for

communicating target positions.

EFFECTS OF WIND

Same techniques of hold-off as with ironsights.

Use of scope allows observation of bullet

impacts not on target. Note the lateraldistance from the target, and place that holdoff to re-adjust and fire.


24/50


25/50

MOVING TARGETS

Utilize the same lead concept as in iron sightshooting.

Lead your target considering the following:

Speed of target

Angle of target movement

Range to target

Wind effects


26/50

MOVING TARGETS CONTD

Angle of movement:

Angles of 0o to 15o should be engaged asstationary targets.

Understand as the angle increases moreHold-off (Offset) is needed.

TRITIUM SAFETY

The ACOG scope is designed to handlefield use, however severe impacts candamage the scope.

Inspect the scope prior to use and afterany severe impacts for tritium lamp glow.


32/50

TRITIUM SAFETY CONTD

If the tritium lamp does not glow, or if yoususpect it may have broken due to damage,treat the scope in the following manner:

Notify your chain of command. Handle only with rubber gloves.

Turn in wrapped in two plastic bags.

Wash your hands.

LEARNING OBJECTIVES

Demonstrate care and cleaning procedures

Without reference, properly mount the ACOGto the M16A4.

Without the aid of references, demonstrate thetwo methods to zero the ACOG.


37/50

If the lenses become dirty, the unit can bewashed with fresh water and a clean cloth.

Be careful to wash the lenses fully beforewiping them with the cloth.

The lenses could be scratched if dirt is pulledalong the lens by the cloth

CARE & CLEANING PROCEDURES


38/50

PRIOR TO MOUNTING THE ACOG


39/50

MOUNTING THE ACOG

Place the ACOG on the receiver rail station thatis suitable for the shooters stock weld and eyerelief. (Most shooters use station T9).

Tighten the interface knobs using your fingers,

then apply an additional 1/8th to a 1/4th turnmore with a screwdriver or multi-tool. Do notover tighten!

Always put the same amount of pressure on

the interface knobs when mounting the ACOG.This affects your BZO retention.

Record the rail station! The ACOG can beremoved and replaced with zero retention only

if the same station is used.

41/50

BZO PROCEDURES

ACOGs come factory preset for most M16A4weapons, as such, only slight adjustments shouldbe made.

DO NOT OVER ADJUST. If you feel tensionincreasing as you adjust, STOP. Turn the ACOGinto the armory. Continued adjustment past thefelt resistance will damage the scope.

The ACOG is only waterproof with the scope capsinstalled and not damaged. Remove and replaceonly when adjusting the scope, and only handtighten.

TWO METHODS OF ZEROING

100 meter zero

25 meter combat BZO

Zero shooting from a supported prone

position using your ruck sack as a rest


43/50

Establish a 100 meter target.

Use a good prone supported firingposition if possible.

Fire 3 single rounds using thetip ofthe chevronas the POA/POI.

(retighten then fire 3 more roundsbefore determining initialadjustments)

Make adjustments for a point of aimpoint of impact.

3 clicks equals 1 inch @ 100

meters for both windage andelevation.

Important: Obtain an accurate zero

Technical:True zero (100m)


44/50

100 meter BZOPOA/POI

Moving the adjuster in the direction of

the arrow moves the strike of the roundin that direction. 3 clicks = 1 For bothelevation and windage

(UP = move impact up)

(R = move impact right)


45/50

Establish a 25 meter target.

Use a good prone supported firingposition if possible.

Fire 3 single rounds using thetip ofthe 300m Post. (retighten then fire 3

more rounds before determininginitial adjustment)

Make adjustments for a point ofimpact1cm belowpoint of aim.

12 clicks equals approximately 1

inch @ 25 meters for both windageand elevation.

Important: Obtain an accurate zero

Technical:BZO

Important: If you BZO the ACOG, confirm true zero as soon as possible at

100m. Make adjustments as necessary.

IMPORTANCE OF A PERFECTZERO

Although the TA31F isNOT a dedicated sniperscope, the importance of obtaining a precisezero must be discussed. If the shooteraccepts a 25 meter zero that is off by only 1inch, the round will impact 32 inches off targetat 800 meters. Therefore it is critical to ensurethe most precise zero possible in order to usethe TA31F to its full potential.

The next slide illustrates this importance.
