The rear sight on my Ruger MKII has come loose and moves when fired. I figured a drop of loctite would fix the problem but I've never used the stuff before. Any tips and also aren't there different strengths/colors? If so, which one do I use?
Thank you |
| The color doesn't really mean the strength of the Loctite... Red 271 is different than Red 222. Fit the number designation with what you are trying to achieve.... Threadlocking, cylindrical locking, disassembly with hand tools, disassembly with heat.. ect... With just about all Loctite brands you can easily use heat to free the parts that are bonded.. there could be damage from the heat to the parts depending on heat source. Some Loctite 609 retaining compound may work for you. Thoroughly clean the parts first. read directions first. |

Hey guys, thanks for the replies so far. I went to midways website and see that they have Loctite 222 Threadlocker Purple on sale. This is listed as being a lower strength version. Will it be strong enough for my intended purpose or should I pay more for the blue 242?
Thank you. |

The purple should do too. Are your issues with the setscrew not staying tight and allowing movement or movement with it tight? Either way you can remove the setscrew and slide or drift out the rear sight and clean it and the dovetail, acetone or alcohol, and reassemble with purple or blue loctite. A little goes a looong way, especially with clean surfaces. I might or might not use it on the setscrew, purple I would feel ok with it though. Give it a day to dry and you should be good to go.
You might find loctite or a permatex brand at a local auto parts store. Save the shipping cost and time. |

Actually this is the basic MK II with a fixed rear sight. Its simply a fixed sight dovetailed in. There are no screws involved in the process. Basically I'm wondering if the Purple 222 will be strong enough on its own to hold the rear sight into the dovetail or do I need the stronger blue 242?
Thanks again guys |
| The purple will probably work. It all depends on how loose the fit is and how big a gap you are trying tofill. Everything should be reasonably tight, unless the sight wants to fall out. Try it and if that doesn't work you can drill and tap a 4-40 setscrew through the rear sight and then clean, glue and tighten in place. Like I mentioned though you can probably find some at and Advanced or Auto Zone locally. Chances are they will have the blue over the purple. I think the retaining version of it would be even better. All I have used in the past was a green color and it was real thin, more so than other forms of loctite. Seems like it was called a shaft and bearing retaining compound. Made for slip fit things. Good luck and let us know how it goes. |
