The bolt (cylinder stop), spring, and plunger assembly is a critical internal component for the Smith & Wesson K Frame Model 10 revolver. The bolt rises through the frame to engage notches in the cylinder, locking it in perfect alignment with the barrel during firing. The spring provides tension while the plunger controls the bolt’s movement. A worn or damaged bolt assembly can cause cylinder timing and lockup issues. This genuine OEM factory part has been inspected and is in good working condition.

Note: Professional gunsmith installation recommended. Proper timing and fitting are essential for safe operation.
