The Sharps MB47 Milled AK Receiver is engineered for precision and durability, inspired by the original Bulgarian milled receivers but enhanced with an integrated AR buffer extension for improved performance. Each receiver is machined from a solid 15-pound block of US-sourced 4140 steel and heat treated to an RC41 hardness, ensuring longevity and reliable operation. The barrel journal is reamed to .9065 inches after heat treatment, providing precise alignment for attachment and minimizing fitting requirements. This receiver is compatible with any milled or standard stamped AKM parts kit, making it a versatile choice for build projects. Attention to detail in manufacturing guarantees a tight fit with an interference of no more than .001 inches, with a maximum of .0015 inches, so measure your barrel accordingly for optimal fitments. Minimal fitting may be needed with the top cover and safety components when used with stamped receiver kits. Designed for semi-automatic operation, the MB47 is suitable for firearm enthusiasts seeking a high-quality, reliable platform to assemble or customize their AK-style firearm. Featuring a sleek black finish, this stripped lower receiver provides a solid foundation for your 7.62x39 caliber build, combining traditional design with modern manufacturing techniques for a professional-grade firearm component.
