Key Features and Benefits

1. 4150 Chromoly Steel Construction

The foundation of this barrel is 4150 chromoly steel, a material known for its superior strength and longevity. Whether you're using your AR-15 for tactical applications, hunting, or target shooting, this durable steel will withstand extensive use without compromising performance.

2. 5.56×45 Chambering

This barrel is chambered in 5.56×45, the standard NATO round that provides impressive velocity and accuracy. It is compatible with both 5.56mm and .223 Remington ammunition, allowing you to use a wide range of rounds for various shooting needs.

3. 1:5 Twist Rate

A 1:5 twist rate means the rifling inside the barrel is designed to stabilize heavier projectiles. This is ideal for shooters who prefer longer, high-velocity rounds or heavier bullets, ensuring that your shots fly straight and true over long distances.

4. Micro Pistol Length Gas System

The micro pistol length gas system is optimized for shorter barrels, allowing for quick cycling and smooth operation. This system ensures consistent performance, even when shooting in rapid succession. It’s perfect for shooters who value reliability in fast-paced environments.

5. Custom Short Gas Tube

A custom short gas tube is included with this barrel, designed to optimize the gas flow for more efficient cycling of your firearm. Paired with the micro pistol gas system, this ensures you’ll have a smooth, reliable shooting experience with every trigger pull.

6. M4 Feed Ramps

The barrel features M4 feed ramps, which enhance the feeding of rounds from your magazine into the chamber. This ensures smooth, reliable cycling and minimizes the risk of malfunctions, especially when using higher-powered or slightly out-of-spec ammunition.

7. Spiral Engraved Markings

To add a touch of personalization, spiral-engraved markings are featured near the break of the barrel. These markings serve both as a unique aesthetic and as an indicator of craftsmanship, giving your AR-15 a distinct look.

8. Matte Rainbow PVD Coating

The matte rainbow PVD (Physical Vapor Deposition) coating is not only visually striking but also functional. This durable finish provides increased corrosion resistance and wear resistance, ensuring your barrel maintains its sleek appearance and smooth performance, even under harsh conditions.
