This Guide Rod assembly is used in the manufacture of the MR918/MR920 pistols. The rod is turned from one piece of 17-4 stainless steel and features a small cross hole to enable easy disassembly and spring replacement. Many rods do not have a cross hole, and you are forced to clamp the rod in something when removing or torquing the screw. This often results in damage to the rod. The cross hole solves the problem.

The rod comes with a Shadow Systems chrome silicon spring manufactured to match OEM specifications.  This is a long wearing, high quality spring that exceeds the performance of a factory spring, particularly when subjected to substantial heat from extended firing.

We use blue locktite during assembly.  If ordering the complete spring assembly, the screw will be torqued and locktited for you.  You can also purchase the assembly without the spring.
