Strangely Brown Posted June 19, 2016 Report Share Posted June 19, 2016 I have an older TR rifle which is a conversion of a No.4; the conversion was done by Geoff Hart (Cheltenham) included fitting a Brindles trigger. The trigger has an allen key adjustment for trigger pull and is prone to slacking off giving a very light pull. Having heard and read contradictory advice on the use of Loctite 290 I thought I would ask for an opinion on here? Link to comment Share on other sites More sharing options...
Shuggy Posted June 19, 2016 Report Share Posted June 19, 2016 Loctite 290 is the green, wicking version. I would apply it very judiciously to a trigger screw as it might wick into the internals and really stuff things up. I would have thought that medium strength (blue) or low strength (purple) would have been better choices. Link to comment Share on other sites More sharing options...
bradders Posted June 19, 2016 Report Share Posted June 19, 2016 I use it for FSBs on ARs because of its wicking properties, although I have currently started using an alternative, Truloc 355 as it is available in smaller quantities My question, are you more concerned with it coming loose or getting it loose?

Coming loose Mark, which it does with regularity. Whilst we don't tend to test triggers in HBSA/NRA historic competitions it would give me a secure feeling I am legal regarding allowed trigger weights.

bradders Posted June 19, 2016 Report Share Posted June 19, 2016 Then glue it up If you need to borrow some, let me know and I'll fetch some down to Bisley next week. You won't have any problems with it Alternatively, nail varnish Link to comment Share on other sites More sharing options...

Thanks Shuggy, I didn't know it came in different wicking grades. Link to comment Share on other sites More sharing options...

Thanks Shuggy, I didn't know it came in different wicking grades. It has a capillary action and its main use if for screws that are already done up, thats why we use it to set FSBs Link to comment Share on other sites More sharing options...
MTLEADFARMER Posted June 19, 2016 Report Share Posted June 19, 2016 On trigger screws I use a dab of the wifes fingernail polish. Link to comment Share on other sites More sharing options...

Shuggy Posted June 20, 2016 Report Share Posted June 20, 2016 Thanks Shuggy, I didn't know it came in different wicking grades. No, the blue and purple grades are not wicking. To use these grades you would have to fully remove the screw, degrease and apply. If you can't remove the screw, it would have to be the green variety. But be very careful and only apply a little!
