Trying to understand if you are placing locktite on the treads prior to assembling GB and then adding LT to screw heads, or just placing LT on screw heads after assembly and tightening of screws.
FWIW, have been using 243 lately, as fasteners are removable with hand tools and 243 is supposed to be more tolerant of oils, which are often present around gun parts.

Yes that's exactly what I meant.
Off topic but has anyone shot a gas block with a temp gun after a couple of magazines full auto?? Might take the what loc tite question off of the table. GH
I'm planning to put Loctite 2422 (medium strength blue) or 2620 (high strength red) on the next gas block screw I come across. I haven't decided which yet.
They are both intended for high heat applications. They are both very chemical and water/moisture resistant.
Although the 2620 is rated "high strength", it's really in between Loctite's standard/common red and blue for holding power at room temp.

For application to set screws or any threaded fastener AFTER assembly - I have used #290 for years - it is a wicking type threadlocker that very effectively works its way down into the threads. All threaded holes and fasteners must be thoroughly degreased prior to application - this is true with any threadlocking product.
Also - some of the 600 series Loctite products are exceptional - shaft locking for cylindical assemblies. I've used #620 and it don't budge!
