5.56 Barrels

Why Choose a 556 Barrel?

A 5.56 barrel is engineered for high-pressure performance, making it the preferred choice for tactical shooters, hunters, and self-defense applications. While a 5.56 NATO barrel can safely fire both 5.56 NATO and .223 Remington rounds, its chamber design is optimized for higher pressures, ensuring better reliability and longevity.

Here’s why a 5.56 AR-15 barrel is awesome

• Versatility – Compatible with 5.56 NATO and .223 Remington ammunition.
• Durability – Handles high pressure, reducing wear and tear.
• Performance – Provides superior power, especially in tactical or hunting scenarios.

Choosing the Right 556 Barrel for Your AR-15

The right AR-15 5.56 barrel depends on your shooting needs. Here’s a breakdown of common barrel options:

• 20-inch 5.56 barrel – Ideal for long-range accuracy and maximum bullet velocity.
• 16-inch 5.56 barrel – The standard length for balanced maneuverability and performance.
• Chrome-lined 5.56 barrel – Offers superior heat resistance and corrosion protection for extended use.
• Stainless steel 5.56 barrel – Designed for enhanced precision and accuracy in competition shooting.

556 Barrel Performance & Pressure Considerations

A 5.56 barrel is specifically designed to handle higher chamber pressures. The 5.56 NATO round generates approximately 62,000 PSI, compared to the 52,000 PSI of .223 Remington. This higher pressure allows for increased velocity and stopping power, making a 556-barrel AR-15 build more effective in demanding scenarios.

For those who require maximum performance, selecting a 556 barrel ensures that your AR-15 is built for resilience, whether you’re in a high-intensity shooting situation or training for long-range accuracy.
