Introducing our precision engineered extended barrel, crafted to mirror the renowned Ed Brown barrel with an extended length for seamless suppressor integration. Designed for the 45 ACP, it features a precise thread size of 0.578 x 28 TPI RH, ensuring wide suppressor compatibility. Each barrel includes a link, link pin, bushing and a robust thread protector for durability and ease of use. For optimal performance in a 1911 platform, pair this barrel with a suppressor equipped with a Nielsen device (booster, kicker or Linear Inertial Decoupler) to maintain cycling reliability. We recommend the black Reign suppressor by Elite Iron for superior craftsmanship and performance. This extended barrel enhances your shooting experience with exceptional accuracy and reliability, whether you're a professional or an enthusiast.
