Installation and Safety
A revolver cylinder is not a drop-in part. A qualified gunsmith must inspect chamber condition and fit the complete cylinder assembly, then verify headspace, endshake, barrel-cylinder gap, timing, carry-up, bolt engagement and chamber-to-bore alignment before firing. Used parts may show normal finish wear and handling marks; the photographed item represents the part and condition offered.
