| I installed a set of tech sights on my 10/22 about a month ago, I used blue locktite and I cranked the hell out of the set screw thinking that combined with the locktite, they'd be on there for life. Since installing them I've shot it three times, in the neighborhood of 5-600 rounds down the pipe. Well, last night at the range the front site all the sudden damn near came off! Any suggestions for the reinstall? I've used blue on plenty of other gun parts never had a problem, but I'm thinking of bumping it up to red, or maybe using an epoxy? |

If you are considering using epoxy (permanent solution), you could drill a slight detent in the barrel to resist the movement and use blue/red lock-tite. I have had similar problems in the past with the cheap flash hiders that they sell at cabelas and I haven't had an issue since.

Three things you need to know about locktite.
Degrease Degrease Degrease The threads and screw MUST be totally oil and grease free or it does not work worth a damn. Take it apart and degrease the threads of both with brake cleaner. Use the appropriate amount and wait 24 hours to use. It should be good to go. |

I've never had a locktited screw come loose in 40 years. Maybe you stripped the threads when you "cranked down" the screw. If it's not stripped you might try degreasing with a mild solvent before you reinstall the sights. Stick with the blue. Yeah, it wouldn't have been the first time in my life i've stripped a thread, so on that suggestion, I took it apart (yeah, I know I don't know why I didn't do that first) No stripping, and shockingly, NO BLUE RESIDUE!!! I swear on my childrens' heads that I put it on it before I put it together. Does that stuff go bad? I put them on during a visit to my parents, it's probably twenty years old, liberated from GM in the late eighties. I guess I'll just reinstall them here in my garage, using my own locktite, that was purchased during this century!  I'm also going to take this opportunity to use the divot idea, that's a good one that I don't think I'd ever have thought of, thanks!! Here are the pics, I SWEAR I put it on there! It must have run off, must have totally changed over the past two decades, imagine that.
