CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion problems with this item be reported so that the problem can be corrected and improvements can be made to prevent the problem in future items.
Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of iron. Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface residue, and/or cracking. Plastics, composites and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are excessive heat or light. Damage from these processes will appear as cracking, softening, swelling and/or breaking.
SF 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM 750-8, The Army Maintenance
Management System (TAMMS) Users Manual.
DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE
Destruction of Army materiel to prevent enemy use shall be in accordance with TM 750-244-2 (Procedures for Destruction of
Electronic Materiel to Prevent Enemy Use).

THEORY OF OPERATION

THEORY OF OPERATION
The M68 Sight, Reflex is a reflex (non-telescopic) sight. It uses a red aiming reference (collimated dot) and is designed for the
“two eyes open” method of sighting. The dot follows the horizontal and vertical movement of the gunner’s eye while remaining fixed on the target. No centering is required.
Front and rear lens covers protect the lenses when the sight is being transported or stored. The front and rear lens covers should always be kept closed when the sight is not in use.
The Comp M2 adjustment caps and battery cap have O-rings that keep out moisture. The Comp M4/M4S adjustment caps have straps and battery cap has an O-ring that keep out moisture. Before immersing the sight in water or using it in the rain, verify that the caps are snug by hand tightening them.

0003-1

WARNING

Removal of the Anti-Reflection Device (ARD) could lead to your detection by the enemy.
NOTE
Keep Both Eyes Open. With both eyes open you will be more aware of your surroundings.
NOTE
A Sight Mount is required only when using the M68 Sight, Reflex with the M16A2 Rifle.
NOTE
The front objective lens is an anti-reflective coated lens system with an Anti-Reflection Device (ARD).
NOTE
These parts are removed by rotation in the counterclockwise direction. DO NOT remove the Back Up Iron Sight (BUIS).
The M68 Sight, Reflex must remain matched with the same weapon, attached at the same slot in the rail system, or be re-zeroed.
Since the M68 Sight, Reflex must be removed when the weapon is stored, note the serial number and the rail slot to enable return of same sight to the same rail slot on the same weapon to retain zero. The serial number is located on the bottom of the sight. Zero weapon if same sight is not returned to the same slot.

BATTERY REPLACEMENT AND CHECK

NOTE

The M68 Sight, Reflex Comp M2 sight uses lithium-manganese dioxide batteries which, when depleted, are to be disposed of in
Accordance with technical bulletin, TB 43-0134, Battery Disposition and Disposal, para 4-5, and local regulations and procedures (contact your local DLA dispostions services for assistance for disposal of equipment). Certain states identify lithium - manganese dioxide batteries as hazardous waste; these states are Alaska, California, Minnesota, Rhode Island, and
Washington at present.
NOTE
Duracell DL 1/3N lithium-manganese batteries are the “preferred” battery. Eveready 2L76, Kodak K58L, Varta CR 1/3N, and
Maxell Gold 2L76 are suitable replacements. Least preferred non-lithium alternatives: 2 each Energizer A76 batteries in series
Or 2 each Energizer 357 batteries in series.
The least preferred battery should only be used in an emergency or when all efforts to attain the recommended battery or preferred alternatives have failed and your mission cannot be completed without the use of the least preferred alternative. The battery life of the least preferred batteries will be less than half that of the preferred batteries.

0005-2

0005
COMP M2—ASSEMBLY AND PREPARATION FOR USE – Continued
NOTE
When the battery is properly installed, the sight will function properly. However, if the battery is not installed correctly, there is a potential for a short circuit. There are three main causes for this condition. The first is unauthorized intentional modification to the sight’s battery housing assembly by bending the prongs on the 6-pronged clip. The second cause is the absence of the rubber
O-ring, which degrades the positive connection with the battery. The third cause is the occlusion of the negative connection post by the foam pad. The pad should allow the spring connector in the center to protrude a slight amount from the top of the pad. If the pad covers the spring post completely, the sight will not function.
CAUTION
Before installing battery cap, inspect threads on battery housing and battery cap to ensure that they are free of moisture and dirt and that the O-ring in the battery cap is present. Inspect the battery housing assembly during every battery change. Ensure that the prongs on the clip do not extend over the top of the foam pad. Ensure that the rubber O-ring is present on the 6-pronged positive connection post. Ensure that the spring connector is not corroded and protrudes slightly from the foam pad. Ensure that the rubber O-ring on the battery cap is present and the battery cap is tightly sealed after every battery change, to prevent corrosion of the interior components of the battery housing. If the spring connector becomes corroded, clean it with a wire brush.

MAINTENANCE ALLOCATION CHART (MAC) INTRODUCTION
The Army Maintenance System MAC
This introduction provides a general explanation of the maintenance and repair functions. The MAC (immediately following this introduction) designates overall authority and responsibility for the performance of maintenance tasks on the identified end item or component. The application of the maintenance tasks to the end item or component shall be consistent with the capacities and capabilities of the designated maintenance levels/classes, which are shown in the MAC in column (4). Column
(4) is divided into two secondary columns. These columns indicate the maintenance levels/classes of ‘Field’ and
‘Sustainment’. Each maintenance level column is further divided into two sub-columns. These sub-columns identify the maintenance classes and are as follows:
1. Field level maintenance classes:
a.
Crew (operator) maintenance. This is the responsibility of a using organization to perform maintenance on its assigned equipment. It normally consists of inspecting, servicing, lubricating, adjusting, and replacing parts, minor assemblies, and subassemblies. Items with a “C” (“O” for joint service reporting) in the third position of the Source,
Maintenance, and Recoverability (SMR) code may be replaced at the crew (operator) class. A code of “C” (“O” for joint service) in the fourth position of the SMR code indicates complete repair is authorized at the crew (operator) class. 0024-1

WP 0024
The Army Maintenance System MAC (continued)
b.

Maintainer maintenance. This is maintenance accomplished on a component, accessory, assembly, subassembly, plug-in unit, or other portion by field level units. This maintenance is performed either on the system or after it is removed. An “F” in the third position of the SMR code indicates replacement of assemblies, subassemblies, or other components are authorized at this level. An “F” in the fourth position of the SMR code indicates complete repair of the identified item is allowed at the Maintainer class. Items repaired at this level are normally returned to the user after maintenance is performed.

2. Sustainment level maintenance classes:
a.
Below depot sustainment. This is maintenance accomplished on component, accessory, assembly, subassembly, plug-in unit, or other portion either on the system or after it is removed. The item subject to maintenance has normally been forwarded to a maintenance facility away from the field level supporting units. An “H” in the third position of the SMR code indicates replacement of assemblies, subassemblies, or other components are authorized at this class. An "H" appearing in the fourth position of the SMR code indicates complete repair is possible at this class. Items are normally returned to the supply system after maintenance is performed at this class.
b.

Depot. This is maintenance accomplished on a component, accessory, assembly, subassembly, plug-in unit, or other portion either on the system or after it is removed. Assets to be repaired at this class are normally returned to an
Army Depot or authorized contractor facility. The replace function for this class of maintenance is indicated by the letter "D" or "K" appearing in the third position of the SMR code. A "D" or "K" appearing in the fourth position of the
SMR code indicates complete repair is possible at the depot sustainment maintenance level. Items are returned to the supply system after maintenance is performed at this class.
