LBE Unlimited 16″ .300 Blackout Black Nitride AR-15 Barrel

The LBE Unlimited 16″ .300 Blackout AR-15 Barrel is an excellent choice for any AR-15 build. It is made from high-quality materials and features a durable black nitride finish. The 1:8 twist rate allows for a wide range of bullet weights to be used, making it a versatile option for any shooting situation. The .300 AAC Blackout is a rifle cartridge developed in the United States for use in the AR-15 carbine. Its purpose is to achieve ballistics similar to the 7.62×39 cartridge in an AR-15 platform while using standard AR-15 magazines at their normal capacity.

This barrel’s gas system is also pistol length, making it function more reliably with a wide assortment of bullet weights and brands and in conjunction with suppressors. It is precision machined to ensure a perfect fit and has an opened gas port optimized for .300 Blackout.

Whether you’re building a new rifle or upgrading an existing one, the LBE Unlimited 16″ Pistol Length 1:8 .300 Blackout AR-15 Barrel is an excellent choice.
