SHARPS MB47 MLLD AK RECEIVER 7.62X39

The Sharps Bros. MB47 MLLD AK Receiver is a precision-engineered stripped lower receiver designed for 7.62x39 caliber builds. Crafted from a solid block of US-sourced 4140 steel weighing approximately 15 pounds, this receiver undergoes heat treatment to achieve a durable RC41 hardness rating. The machining process ensures a barrel journal reamed to .9065 inches post-heat treat, providing exceptional fit and reliability.

Inspired by original Bulgarian milled receivers, the MB47 features an integrated AR buffer extension, combining classic design with modern enhancements. Weighing roughly 2 pounds, it is compatible with both milled and stamped AKM parts kits, offering flexibility for various assembly preferences. Minimal fitting may be necessary when pairing with stamped receiver kits, particularly around the top cover and safety areas.

Finished in a black oxide coating, the Sharps Bros. MB47 receiver balances rugged durability with a refined aesthetic. This receiver serves as a robust foundation for custom AK-style firearm projects, ensuring consistent performance and longevity.
