30-6 Posted February 20, 2018 Report Share Posted February 20, 2018 When I recently purchased a sauer 100 rifle in .223 I also got a recknagel picatinny rail for the versatility of day scope and photon. The screws only come through the rail a couple of mm and look about a 3mm thread. Trouble is after a zeroing session, all 4 of the screws are coming loose. I done them up with the supplied torx key to what I thought was a sensible tightness. I did wipe the top of the action with an oily cloth prior to fitting. So, is it possible that the threads are slightly oily and not staying tight ? Or do I need to apply some sort of thread lock after degreasing ? Would this be advisable or a bad idea ?

welshwarrior Posted February 20, 2018 Report Share Posted February 20, 2018 Applie a thread lock blue non permenant so they can be removed is best. Quote Link to comment Share on other sites More sharing options...

30-6 Posted February 20, 2018 Author Report Share Posted February 20, 2018 Just looked on Alan Rhone's website ( where I bought the rail ), on the advice section, and they recommend " loctite 278 " as the product to use. Quote Link to comment Share on other sites More sharing options...
