Just bought a troy front sight it's going on a railed gas block and the instructions say to loctite it. I really don't want to get a bunch of crap on this sight has anybody had issues with it coming loose?

I've had a pair come loose that I didn't use loctite on. Only happened once so I don't know if it is common or not though. A very small amount of blue loctite shouldn't hurt anything or make any kind of mess. I'd stay away from red.

I use blue on anything rail mounted. Just a tiny drop won't make a mess of anything.

No need for LocTite. A little grease and the proper torque value is all that's needed.

While not a Troy fan, I have found that most rail mounted sights benefit from a drop of Loctite Blue.  I use it still on the screws on scope rings too.   It is harmless, does not interfere with removal, and is good insurance against movement.  Yes, anything depending on relatively light torque, as most sight screws do, can and will eventually loosen without some kind of thread lock.

I've started used purple Loctite #222 for small screws because it will still prevent screws from coming loose but it's easier to break with just tools.

I remember reading an article in SWAT (I think by Pat Rogers) advising the use of thread locker on sights, mounts, etc. Cheap insurance on a serious use gun. This of course is in addition to using good hardware and appropriate torque settings.

I'm 64 years old.  Old dude with old school thinking.   Before Loctite was invented, we were using ordinary varnish.  Just a drop of varnish on the screw threads we would put on scope bases mounted to bolt action receivers and on the scope ring screw threads worked as well as Loctite does today.  And, it would break loose with ordinary hand tool torque.   While specialized thread lockers represent an advance, the underlying concept remains:  If it can shoot loose, it will.
