This Ruger Tech Tip provides a detailed, step-by-step guide on how to reassemble the Ruger LCR revolver after cleaning. It emphasizes critical torque specifications for the ejector rod and frame screw, highlighting potential pitfalls like over-torquing. The instruction covers building sub-assemblies for the cylinder crane and fire control unit, culminating in the final assembly and function check.

Quick Summary

When reassembling a Ruger LCR, ensure the main frame screw is torqued to 23-27 inch-pounds. The ejector rod has a left-hand thread and should only be turned 1/16 to 1/8 of a turn past finger-tight to prevent breakage. Over-torquing can lead to significant damage.

Frequently Asked Questions

What are the critical torque specifications for reassembling a Ruger LCR?

The main frame screw on a Ruger LCR requires a torque of 23-27 inch-pounds. Upper screws, if present, need a much lower torque of 3-9 inch-pounds to prevent stripping the polymer frame.

How do you properly tighten the ejector rod on a Ruger LCR?

The ejector rod has a left-hand thread and should be tightened counter-clockwise. After finger-tightening, use vice grips with a cleaning patch to turn it only about 1/16 to 1/8 of a turn to avoid snapping it.

What tools are necessary for Ruger LCR revolver reassembly?

Essential tools include vice grips, a torque wrench (23-27 inch-pounds), a number 10 Torx bit driver, a 1/16 punch, a cleaning patch, and safety glasses. An ejector support tool is also recommended.

What is a common mistake to avoid during Ruger LCR reassembly?

A critical mistake is over-torquing the ejector rod, which can easily snap it off. Another is over-torquing the upper screws, which can strip the polymer frame and cause the screw to spin freely.
