Can I just tighten these or do I need to blue loctite?
Just loc-tite 'em. They’ll be fine.
Just speaking from my own experience so it’s not saying much, but I never loctited mine and they’ve been fine. I’ve used DD Aimpoint T-1 mounts, DD Iron sights (both front and rear), and have never used loctite on them. They’ve all interestingly kept their zero even after more than 5000 rounds. I think DD has some sort of special screw or compound in the threads that hold pretty well so I don’t think loctite is needed. In fact, I don’t think the instruction manual for the DD T-1 mount or sights mention required loctite. Someone correct me if I’m wrong.
Any accessory or screw/bolt that experiences recoil and does not need to be removed on a regular basis, should have a thread locker applied. Thread locker can be anything from a commercial product to fingernail polish. The thread locker should be chosen based on the amount of heat the part will experience and if the part will ever need to be removed.
Very few manufactures recommend thread locker, maybe they figure if it falls off you will have to buy another one.
I am not taking a dig at the OP per se. But, I am rather amazed at the amount of posts lately that are utterly simple or redundant.
The Loc-tite issue has been discussed many times over. Some manufacturers do recommend using thread locker and some actually put in on the screws when they make them.
Anyone who has used an optic for any amount of time should know that the vibrations from shooting can and will loosen the screws on mounts, rings, etc…
Thought this would be a place to ask the experts. I see that the Daniel Defense rear sight appears to have some type of coating on the threads. I thought, perhaps, that made the loc-tite un-needed. These are new sights to me, and the manufacturer does not include recommendations to use loctite on either.
Iraqgunz, you always pick on my posts. I don’t know if you have a problem with me personally or what your deal is. I’m sorry that I’m not an expert enough for you, and that my questions are too “simple” and “redundant.” The search function, previous threads, do not always answer every question. If they did, we might as well just lock up all new posts. I thought that part of the purpose of these forums was to ask questions that we had of the experts. Why don’t you PM me a list of the topics I can’t post about, so I can save you the time of locking or deleteing my threads. Speaking of which, guess you’ll be locking this one up and deleting it now. I don’t cause issues or arguments, I’m not rude, and I contribute where I can. GET OFF MY BACK!
Just my two cents. Loctite is prudent, but it’s my understanding that the DD rear sight has some kind of locking insert like a miniature helicoil to keep it from loosening. Looking at mine I see what appears to be a spring insert in the threads.
Interesting. Yes, if I had to error onone side it would be with the loc-tite.
I don’t know why you think I am picking on you…maybe there is a pattern? In any case as I stated I am not digging at you per se, but there have been a rash of threads lately that are just plain silly.
I just used the ORANGE search button and typed in Loctite Sight Mounts and stumbled upon an incredible amount of threads that discussed putting Loc-tite on screws, sights, etc…
Blind pin and weld them… Then stake them with a Moacks. It’s the only way to be sure.
:haha:
OP, it can’t hurt not to. Are you going to be removing your fixed sights a lot? No? Then I wouldn’t see a problem with some 242 locktite on there. This shit is bananas… 
I don’t think IG was picking on you, just a very monotonous type question that has been beaten to death and really isn’t that important to begin with. I wouldn’t get sore over it.
Pre se my foot, you pointed that directly at me…and how many of those posts you found specifically covered Daniel Defense rear sights and Troy fixed fronts. At M4carbine, if it’s been generally covered, no specific questions, huh? Just don’t know how any of this is worth a moderator’s time. If this was an overly covered issue, unworthy of anybody’s notice, than nobody would have responded.
Thanks for everyone who posted, the info was helpful.
Thats what I do! :sarcastic:
You gotta stake your weapons light
OP I have been here awhile, I can honestly say IG is not picking on you, I have seen that response numerous times.
You gotta see where he’s coming from, there is a PLETHORA of information that has been covered over and over and over, instead of starting a new thread on something, check out the search thread.
All the info is there.
Instead of it all being in one place, it gets spread out over multiple forums making it more difficult to find, which turns into a shit ton of new threads on the SAME topic.
People respond, as I did, in an effort to be nice and guide you on your way. You may not be able to find things about fixed sights specifically but you can find links about using blue/242 locktite on screws for: FSB mounts for lights, gear sector/vtac/vltor etc light mounts, grip screws, selector screws, sight mounts fixed or flip, etc. From there you could reasonably deduce that yes…yes you would be well advised to locktite mount screws.
It is not the moderators job to coddle you - if you’re out of line, they’ll tell you. That’s what is nice about things around here. No sorority, talk behind your back bullshit. You know where you stand and if you’re in line or out. Fit in or fuck off kinda thing.
Is there a moacks for that? :sarcastic: I need to call Ned!?
This thread actually has me thinking…has anyone here actually had DD sights or mounts come loose or back out on them when they didn’t use loctite?
There’s definitely that red helicoil or something like that present. I don’t know much about it or how it works. Surely somebody here knows its properties or if it rids the need for blue loctite on the irons.
One other thing…it’s been awhile since I installed the T-1 onto the DD micro mount, but if I remember correctly, I did loctite the screws mounting the actual optic to the mount. This tells me that maybe the instructions may have said to loctite the optic to the mount, but not necessarily the mount screws when securing them to the weapon…can’t say I really remember though and unfortunately the original instructions got lost.
:sarcastic::sarcastic::sarcastic:
I’ll get the silver sodder…
Didn’t think that M4carbine was this kinda place. Guess that says it all.
KAC micro front loosened up on me after about 200 rounds. Locktite fixed it. No experience with DD though, but it’s the same idea.
In terms of asking questions that have been covered…I think so? I don’t wanna speak outta turn though.
