The 5.56x45mm NATO cartridge is a popular choice for a wide variety of firearms, known for its relatively small size, lightweight nature, and impressive stopping power at shorter to medium ranges. This makes it a favorite among military forces and civilian shooters alike. But what guns actually use this versatile round? Let's dive in.
Military and Law Enforcement Rifles
The most common association with 5.56 ammo is undoubtedly with military-style rifles. Many nations' armed forces utilize weapons chambered in this caliber, leading to widespread adoption and a robust aftermarket. Some of the most prominent examples include:
-
M16 Rifle: A classic and iconic weapon, the M16 rifle family (including the M4 carbine) has been a staple of the US military for decades. Its reliability and effectiveness have solidified its place in history and continues to see use in various configurations.
-
M4 Carbine: A shorter, more compact version of the M16, the M4 is highly popular among military personnel, offering improved maneuverability in close-quarters combat situations.
-
HK416: Developed by Heckler & Koch, the HK416 is a highly reliable and accurate rifle favored by many special forces units worldwide. Its enhanced gas system offers superior performance in adverse conditions.
-
FN SCAR: The FN SCAR (Special Operations Forces Combat Assault Rifle) is a modular system offering adaptability for various combat scenarios. It's known for its robust build and exceptional accuracy.
Civilian Sporting Rifles and Carbines
The popularity of the 5.56 cartridge extends far beyond military applications. Numerous manufacturers produce civilian-legal semi-automatic rifles and carbines chambered in 5.56 NATO. These frequently mirror the design of military rifles but are designed to comply with stricter civilian regulations. Examples include:
-
AR-15 Platform: The AR-15 platform is perhaps the most prevalent civilian 5.56 rifle. A wide array of manufacturers produce AR-15s, offering a staggering level of customization and parts availability. This makes it highly adaptable to individual needs and preferences.
-
SIG Sauer M400: SIG Sauer's M400 line offers reliable AR-15 style rifles with a strong reputation for accuracy and durability.
-
Bushmaster XM15: Bushmaster, a well-known firearms manufacturer, produces various AR-15 style rifles for civilian use, offering a good balance of performance and price.
Other Considerations
While rifles dominate the 5.56 landscape, it's worth noting that other firearm types can also utilize this cartridge:
-
Pistols (rare): While less common, some pistol designs exist that are chambered for 5.56. These are generally less prevalent due to the cartridge's length and recoil characteristics.
-
Submachine Guns (rare): Similar to pistols, submachine guns chambered in 5.56 are relatively uncommon.
