Smith & Wesson Model 686 L Frame Bolt Assembly .357 Magnum, Part# 68610

Smith & Wesson Model 686 Bolt Assembly – Part# 68610

This is a genuine factory Smith & Wesson bolt assembly for the L Frame Model 686 revolver. An old-style used part in serviceable condition — a reliable, cost-effective option for restoring proper cylinder function on your 686.

In S&W revolver terminology, the bolt (also called the cylinder stop) is the component that rises to lock the cylinder in precise alignment with the barrel at the moment of firing. A worn, chipped, or broken bolt causes cylinder wobble, poor lockup, and degraded accuracy. The bolt assembly includes the bolt and associated components as a complete unit.

Model Compatibility

Note: Bolt assemblies are frame-specific and not interchangeable between J, K, L, or N Frame revolvers. Always confirm your exact model before ordering. Model numbers are stamped on the frame behind the yoke when the cylinder is swung out. Pre-1957 revolvers may not have a model number — contact us with your serial number for assistance.

Installation

Bolt assembly replacement requires side plate removal and disassembly of the lock work. Cylinder timing must be verified after installation to ensure safe, reliable lockup. We recommend installation by a qualified gunsmith.
