What Scope does the military use on M4?
The M4 carbine is a widely used firearm in the United States military, and its optic choices play a crucial role in enhancing its performance. While the M4 is versatile enough to be used in various roles, its effectiveness relies heavily on the attachment of a suitable scope.
Standard Issue Optic
The United States Army, in particular, issues the M68 Close Combat Optic (CCO), a hybrid sight that combines the benefits of a red dot reflex sight and a 4x magnified optic. The M68 CCO is designed to provide close-quarters battle (CQB) capabilities while also enabling snipers to engage targets at longer ranges.
| M68 CCO Key Features
- Hybrid design for CQB and mid-range engagements
- Red dot reflex sight for quick target acquisition
- 4x magnification for sniper-style engagements
- Flip-up lens cover for increased durability
- Paralax-free design for reduced reticle movement
MARSOC and Special Forces
The Marine Corps’ MARSOC (Marine Corps Special Operations Command) and other special operations forces often employ the Trijicon Advanced Combat Optical Gunsight (ACOG) on their M4s. The ACOG is a versatile, rugged, and highly accurate optic designed for engagement at distances ranging from CQB to 600 meters.
| ACOG Key Features
- Designed for CQB, precision rifle, and medium-range engagements
- 4x magnification with a 32mm objective lens
- Illuminated reticle with multiple brightness settings
- Rugged and weather-resistant construction
- Picatinny rail mounting
Other Optic Options
In addition to the standard-issue M68 CCO and the ACOG, other optic options are used by military units depending on their specific needs. Some examples include:
- EOTech 512/552 holosights, which are often used by Special Operations Forces for their high-magnification and ruggedized designs.
- NVD (Night Vision Device)-compatible optics like the Knight’s Armament Company (KAC) M145, designed for use with night vision devices.
- Prismatic scopes like the Leupold VX-3 and Trijicon RM05, which offer a flat, wide field of view and are suitable for engagements at medium to long ranges.
Key Considerations
When selecting an optic for the M4, several key factors should be considered:
- Durability: Military operations can be harsh, so it’s essential to choose an optic that can withstand heavy use and extreme environmental conditions.
- Clear sight picture: A clear sight picture is critical for accuracy, so optics with good glass quality, parallax-free designs, and easy reticle adjustment are vital.
- Range engagement: Different optics are suited for different engagement ranges, from CQB to sniper-style engagements.
- Compatibility: Ensure the chosen optic is compatible with the M4’s rail system and does not interfere with the operation of other accessories.
- Battery life: Military operations often involve prolonged use, so optics with long battery life or non-lithium batteries are advantageous.
Conclusion
In conclusion, the United States military uses a range of optics on their M4 carbines, from the standard-issue M68 CCO to the advanced Trijicon ACOG. When selecting an optic, consideration should be given to durability, sight picture, range engagement, compatibility, and battery life. By understanding the available options and their characteristics, military personnel can make informed decisions about the optics that best suit their needs, enhancing their overall effectiveness in the field.
