The M72B1 is widely regarded as one of the finest RPK-pattern rifles ever fielded — heavy-profile barrel, robust construction, and reliability that won’t quit. Original barrels are one of the hardest components to source for any serious M72 project, and unlike the reproductions out there, these came from actual military production.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOriginal Yugoslav M72B1 RPK military surplus barrel — NOT a reproduction\u003c\/li\u003e\n\u003cli\u003eChambered in 7.62x39\u003c\/li\u003e\n\u003cli\u003eCold hammer forged military production\u003c\/li\u003e\n\u003cli\u003eHeavy-profile RPK barrel\u003c\/li\u003e\n\u003cli\u003eGenuine military surplus component\u003c\/li\u003e\n\u003cli\u003eDid NOT pass the muzzle wear test — priced accordingly\u003c\/li\u003e\n\u003cli\u003eNot sorted for bore condition\u003c\/li\u003e\n\u003cli\u003eGreat for restorations, display builds, and parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCondition — The Straight Talk\u003c\/h3\u003e\u003cp\u003eThese barrels are military surplus — previously installed, previously used, and very worn.
