Thanks to both of you for the Rocksett info.

Thanks.

Thanks to all for any other advice....

Thanks.

Interesting...is it more glue like than a Blue thread locker? Im reading it becomes very hard? Is it similar disassembly as the heating techniques of the blue or esp red threadlockers? Also, thanks for taking time to share the pictures.

The pic rail on top of my M4 that came from the factory always comes loose after maybe 75 or 100 rounds. The gun is barely 3 months old. Any sights i have mounted becomes floppy, of course. All 5 screws come loose! I tried Permatex Blue Gel, but it didnt work - Im not even sure it bonded properly, even tho i prepared screws and holes with a degreaser - but didnt acetone. The threads are all intact. Any expert advice? I see theres an idea elswhere that Loctite 243 [not 242] for aluminum to steel is proper for these tiny screws placement into the top of the receiver to hold the pic rail in place, but i dont kno what the screws and receiver metals are made of for the pic rail. Is this chemical answer the best way to go? Is there other tried and true options out there? Thanks for any help.
