One place Loctite is really useful is on the handguard screws.

I eventually realized that the handguard screws had come loose due to the recoil vibrations. I put some blue Loctite on the screws and never had another issue.

Are going to ignore LocTite 222 MS (Minimum Strength) (Purple)? It is my favorite for optics screws and anything attached to the hand guard. I learned my lesson long ago to not use Blue (242/243) on small screws despite what some accessory manufacturers recommend. Easy to end up twisting the head right off a small screw. But never had a problem with Purple/MS on small hardware... that is what it is designed for, fasteners 1/4" and under, including for aluminum. Henkel, the manufacturer of Loctite, states that 242/243 (medium) is intended for fasteners 1/4" / 6mm in diameter or larger (up to 20mm).... not many gun screws in that range.
@autumnfragrance7185

You can use low strength loctite 222 on the bolt release thread screw found on some billeted upper receivers... nowadays, even some forged uppers use this screw. You can use medium strength (blue) loctite (242 or 243) on handguard rail accessories. 243 provides better oil resistance. Medium strength loctite can also be used on the screws found on some trigger guards. You can use Loctite 246 or Permatex red on gas block screws. You can use Rocksett on a muzzle device.

Agree with everything said. I never use Loctite on anything that attaches to any of the receivers from the front (barrel) or the back (extension tube). The one exception to what was discussed that I make is the grip. I use blue Loctite there. I also use blue Loctite when attaching accessories to the receiver such as lights, scope rings, foregrips, or secondary sights. I also use blue Loctite for the scope mount screws that hold the actual scope in place. I find that all these accessories have a tendency to come lose after prolonged use.

THANK YOU!!! so many newbies try loctite and it makes me wince. I had a guy who red loctited his castle nut and it was BEOTCH to get off. Especially because the owner who I had to help replace that tube was the 2nd owner and didn't realize that the 1st owner used red loctite AND staked it. So you can be assured we replaced that damn tube afterwards. the ONLY place I would consider it a "ok, I wouldn't do it except when I was a newb, but it's not gonna kill it" is a little blue loctite on the pistol grip screw. It's not gonna cause an issue there as long as you don't red loctite it. It's not in any way needed, but if you did that on a build I wouln't start ripping your hair out and thinking you ruined your lower (if you red loctited it...welllllllllllllllll lol)

If you have a serious use or duty use AR or take a rifle course and shoot upwards of a thousand rounds in a weekend you will find that a castle nut needs staked, handguard screws need loctite and the gas block needs minimum to be dimpled but pinned in place is even better and there are torque specs for a reason. The best way to learn this and what works is by actually shooting your AR a lot, you should not have anything working loose. Also scope mounts and rings should have loctite and proper torque specs. When it counts you need to be able to depend on your firearm.

I probably put 500 rounds through the rife so far with the blue Loctite with no loosening of the optic. I have red Loctite (high) but have never used it. The Romeo5 only has one machine screw holding the optic onto the rail, and I believe two machine screws would be a better design.

There are other compounds that can be used to safely retain/ secure components-- there's a transparent orange compound (forget what it's called) that's safe for mixed metal connection points and threadings alongside polymer and metal screw connections, but proper torque is always the first and foremost thing you should do for proper retaining, an appropriate compound (and an appropriate amount applied) should only be used if things keep vibrating loose or get knocked loose and won't stay tight, and you don't want to over-tighten and damage threading components like the handle/ grip retainer screw or stake the castle nut. And about the statement "if it was needed the military would do it"-- actually, from time to time they do utilize thread locking compound, especially due to how worn our weapon systems can get with certain components. Our Armorers have to be adaptive (especially on deployment) when replacement/ new parts aren't readily available or take forever to come in after the order request has been submitted and the weapon systems have be kept in the fight. I'm glad to see the Brownells crew are actually reading the comments!

FYI, torquing a bolt or nut effectively is bending threads opposite direction. So in effect over torquing will ruin threads and done enough properly will also render them expired. Specification assuming it accounts for material type and intended force to contain will usually avoid this. So in effect torquing is the answer here. Just remember there is a failure point. See RN-50 cap failure for the more extreme case. Each round fired was instantly torquing the threads with the cap. In my opinion your castle nut should not move with reasonable tightening. I guess maybe a blaster using 50 Beowolf maybe encourage it to move. Oh and I appreciate an actual answer on why you do not want to use it with reasonable points. However Green Loktite is used to secure engine sleeves, its permanent once applied.

2 other problems with putting loctite on your barrel nut, if you put lock tight on and use a torque wrench it will affect your torque readings so they are not accurate, and if you put loctite on as a substitute for a torque wrench and later get a torque wrench to use on it then it will again affect your torque readings if you don't get every last bit of it off (and the heat for shooting may make it useless anyway)

will add one more area only - for ambi-selectors like a Colt M4/Colt Canada C8, a small dab of blue loctite on retaining screw for the right side selector is important. otherwise - not part of the AR but on it, is blue loctite on attachments like lights and sights and non-throw lever optics....as they will come loose when least expected. I have seen many surefire M600's come loose even when the thumbscrew was tightened with noticeable force using a screwdriver. and just to add - a little thread lock goes a long way...I prefer the sticks vs the liquid.

I put my guns together with JB weld, it's stronger than loctite and I've never had one come apart. It also handles the heat with no problem.

I use a little blue loctite on my light, foregrip, and a tad on the optic. Only things that might take a beating as extremities. Torqued to spec of course.

I do locktite my barrel nut but only a small drop about as much as you might put on a small screw never had a problem. I also use a small amount to fill the space between the barrel and receiver so once it dries there is no wiggle between them, and that is a retaining compound that can be cleaned off pretty easily after removal.

Locktite on the buffer tube also tends to run down the buffer retaining pin.

Only time I've used loctite(blue) on an ar was for optic mount screws. I could probably use something else but I feel some extra security with locking the threads down a little bit to keep the optic solid in place.

I use a touch of blue loctite in my aero receivers' threaded pins. That's it. If I need to remove them, I could always break the bond with a drop of acetone but they break free pretty readily without it.

Accurate. I use rocksett on my muzzle device and the gas block set screws. People seem to think that it is harder to get off but it is somewhere between blue loctite and red loctite but WAY more temperature resilient. People that use loctite on their barrel nut.....makes no sense. It essentially stops working after the first few shots due to heat anyway and they should really be using aeroshell which is nearly the opposite of loctite. What about loctite on scope mount screws? That is the only place I use loctite. Maybe....maybe on anti-rotation hammer/trigger pin installs although some companies like Geissele don't want you to lock those pins in place.

I prefer to use Vibra-tite for the pistol grip screw. I also put a thin layer on the threads where the buffer tube threads into the lower. Let it cure for 15 minutes before threading the tube in. Vibratite behaves more of a shock absorber and it doesn't 'harden' like loc-tite - plus its easy to remove. Then I apply aeroshell to the threads before threading the castle nut on, torque it, and stake it. Overkill? Maybe. Also, its super easy to clean off threads with brake cleaner.

It seems counterintuitive to use loctite in most places along the bore axis. I use never-seize, especially on the barrel fitting, barrel nut, muzzle device, and buffer tube. The places I use blue loctite are the handguard screws and a dab on the grip screw and the bolt catch pin screw (if it's threaded).

As a Loctite certified engineer that has also been through the Bickford training for joint design, I am called an idiot by those that bought the wrong 6 ml tube of Loctite at the auto parts store. They spent $7 on Loctite once, so they know better than me. Obviously. Loctite should NOT be used on the castle nut or barrel nut, like mentioned in the video. There are specific procedures to install those fasteners. Those nuts are retained by different locking mechanisms. The PURPLE Loctite 222 product is pretty much the only Loctite for use on the AR. That is the proper product to avoid issues with stripping the drive mechanisms or shearing screws during any removal process. PURPLE Loctite 222 is the proper product for fasteners up to 1/4" or 6mm. Setscrews are generally a dumb design, but setscrews on a gas block with or without Loctite, dimpling, or magic fairy spells are a really dumb design. The setscrew designs fail any Bickford analysis, especially with thermal cycling, Junker tests, or impulses. Joint prep to degrease the male and female threads is important with Loctite. Proper torque with a torque limiting screwdriver is critical. The "internet experts" are missing those tools, but they know better than me. On the production line we use electric torque driving tools that automatically drive fasteners and send the fastening data to the database that is tied to each serial number for tracking. The least a person can do is use a torque limiting screwdriver, if they want to work on guns. There is also a need to bias accessories FORWARD when fastening items to an AR for proper retention during the recoil impulse, Loctite or no Loctite. The inertia of the accessories will drive the accessories forward during recoil, so take out any play during installation. "Glock front sights fall off all the time." That does not happen when using the proper fastening methods. Loctite 222 and 3.5 lb-in of torque is all it takes. I have those driving tools and have never had a customer come back with a failed front sight in almost 30 years. The "internet experts" and "top instructors" have these failures all the time. What explains the difference? They are untrained, lack the proper tools, and are full of themselves.

That 'resin' as you call it, is, most often, a product made by Loctite called Vibraseal and is what is found on Magpul screws. The stuff can be hard to find, but it's well worth getting and using as it does a great job of keeping screws, nuts and bolts from 'vibrating' loose, hence the name "vibraseal". This is what I use and never do I use 'thread locker'.

Wondering why someone would stake the castle nut if their usual post-shooting maintenance program involves checking for loose fasteners?

If it comes loose while shooting and the receiver extension rotates, checking after isn't going to help you find the rear takedown pin detent and spring at the range.

Castle nuts don't come loose unless you NEED them to not come loose. Proper assembly means you don't need to check for loose fasteners afterward. I torque stripe mine all the same though.

some thoughts, 1 loctite has several med strength items some of them are red. 2 if 2 drops of loctite on your castle nut let dry then install stripped your threads they were fail if you put torque to them. if you flood the area and install wet you get what you disserve. 3 none of that says use loctite on your rifle. just some thoughts from someone who has to use it on pumps and other items in a boiler and chiller plant. i don't stake or loctite my rifle i just make a mark with a soap stone across the nut and tube, if they don't line up i need to check. haven't had to yet.
