LBE Unlimited 18″ .223 Wylde Black Nitride AR-15 Barrel

The LBE Unlimited 18″ .223 Wylde Black Nitride AR-15 Barrel is a do-it-all barrel for hunting and longer-distance shooting. This barrel is chambered in .223 WYLDE, which means that it can safely fire both .223 Remington and 5.56 NATO ammunition. Measuring 18 inches in length, the LBE Unlimited Barrel is an excellent choice for a variety of shooting applications including hunting, target shooting, and tactical use due to not being a full 20″ or losing velocity with a shorter barrel.

The barrel’s black nitride finish provides durability and corrosion resistance, ensuring that your rifle will stand up to heavy use and harsh weather conditions. The 1:7 twist rate ensures excellent accuracy and consistent performance, making it an ideal barrel for competitive shooting and precision applications.

The rifle-length gas system and .750 gas block compatibility make it easy to install on your rifle, and the compatibility with a variety of gas blocks means that you can customize your rifle to suit your needs. Whether you’re a seasoned shooter or a beginner, the LBE Unlimited Barrel is a great choice for anyone looking for a reliable, high-performance barrel for their AR-15.
