5.56 Ammo Guns: A Comprehensive Guide to Rifles and Cartridges
The 5.56x45mm NATO cartridge, often simply referred to as 5.56 ammo, is a ubiquitous round in the world of firearms. Its widespread adoption by military forces and civilian shooters alike stems from its balance of manageable recoil, effective range, and relatively lightweight nature. This article delves into the world of 5.56 ammo guns, exploring the rifles chambered for this cartridge, the various types of 5.56 ammunition available, and key considerations for choosing the right firearm and ammunition for your needs. Understanding the nuances of 5.56 ammo is crucial for responsible gun ownership and effective use.
The History and Development of 5.56 Ammunition
The 5.56 cartridge was developed in the late 1950s as a response to the perceived shortcomings of the 7.62x51mm NATO round, which was the standard cartridge for NATO forces at the time. The 7.62 was powerful but heavy, leading to soldiers carrying less ammunition and experiencing more recoil. The 5.56 was designed to be a lighter, faster, and more controllable round, allowing soldiers to carry more ammunition and engage targets more effectively at shorter to medium ranges.
The initial version of the 5.56 cartridge was the .223 Remington, which was commercially available before the adoption of the 5.56 NATO standard. While the two cartridges are similar in dimensions, there are slight differences in chamber pressure and case thickness. It is generally safe to fire .223 Remington ammunition in a rifle chambered for 5.56 NATO, but it is not recommended to fire 5.56 NATO ammunition in a rifle chambered for .223 Remington, as the higher pressure could potentially damage the firearm. Always consult the manufacturer’s recommendations for your specific firearm.
Popular 5.56 Ammo Guns: Rifles and Platforms
Numerous firearms are chambered for the 5.56x45mm NATO cartridge. Here are some of the most popular and widely used:

M16 and M4 Rifles
The M16 and M4 rifles are the standard-issue firearms for the United States military and many other armed forces around the world. These rifles are based on the AR-15 platform but are typically select-fire, meaning they can fire in semi-automatic or automatic modes. While civilian ownership of select-fire firearms is heavily regulated, the M16 and M4 have significantly influenced the design and development of modern 5.56 ammo guns.
Steyr AUG
The Steyr AUG is a bullpup-style rifle chambered in 5.56. Its bullpup design places the magazine behind the trigger, resulting in a shorter overall length without sacrificing barrel length. The AUG is known for its accuracy, reliability, and ambidextrous controls. [See also: Bullpup Rifles: Advantages and Disadvantages]
FN SCAR 16S
The FN SCAR 16S is a semi-automatic rifle based on the FN SCAR (Special Operations Forces Combat Assault Rifle) platform developed for the U.S. Special Operations Command. It is known for its ruggedness, reliability, and modular design. The SCAR 16S is a popular choice among shooters who demand a high-performance 5.56 ammo gun.

Types of 5.56 Ammunition
Various types of 5.56 ammunition are available, each designed for specific purposes. Understanding the different types of ammunition is crucial for selecting the right round for your intended use.
M193
The M193 is a 55-grain full metal jacket (FMJ) bullet. It was the original military standard for the 5.56 cartridge and is still widely available today. M193 ammunition is generally inexpensive and suitable for target shooting and training.
M855
The M855 is a 62-grain FMJ bullet with a steel core penetrator. It is designed to penetrate soft body armor and is the current military standard for the 5.56 cartridge. M855 ammunition is commonly available but may be subject to restrictions in some areas.
Hollow Point (HP)
Hollow point ammunition features a cavity in the tip of the bullet that is designed to expand upon impact. This expansion creates a larger wound cavity and increases the likelihood of stopping the target. Hollow point ammunition is a popular choice for self-defense.
Soft Point (SP)
Soft point ammunition features a lead core exposed at the tip of the bullet. Similar to hollow point ammunition, soft point ammunition is designed to expand upon impact, creating a larger wound cavity. Soft point ammunition is often used for hunting.
Tracer
Tracer ammunition contains a pyrotechnic compound that ignites when the bullet is fired, creating a visible trail. Tracer ammunition is used to help shooters track their shots and is often used in military applications. Civilian use of tracer ammunition may be restricted in some areas.
Choosing the Right 5.56 Ammo Gun and Ammunition
Selecting the right 5.56 ammo gun and ammunition depends on your intended use, budget, and personal preferences. Consider the following factors when making your decision:
Intended Use
How will you be using the firearm? If you plan to use it for target shooting and training, an AR-15 rifle with M193 ammunition may be a good choice. If you plan to use it for self-defense, a compact AR-15 pistol with hollow point ammunition may be more suitable. If you plan to use it for hunting, a rifle with soft point ammunition may be the best option.
Budget
5.56 ammo guns range in price from a few hundred dollars to several thousand dollars. Ammunition prices also vary depending on the type and quantity. Set a budget before you start shopping and stick to it. [See also: Budget-Friendly AR-15 Builds: Getting Started Without Breaking the Bank]
