Replace a worn or damaged bolt head with this precision-machined Mauser MO3 right-hand bolt head in a tough steel (ST) finish. Engineered to Mauser MO3 pattern tolerances, the bolt head provides consistent locking, reliable extraction and long-term durability under regular use. Its steel finish is functional and hard-wearing, making it suitable for service rifles, hunting rifles, and workshop spares.
This bolt head is ideal for gunsmith replacements, rebuild projects, or carrying as a spare on the range. Confirm whether the extractor and ejector are included, and always have installation, headspacing and function checks performed by a qualified gunsmith before firing. Correct installation ensures safe operation and consistent performance with your MO3-pattern action.
