Is Blue Loc-tite best for adjustable sights?

I want to lock the adjustment but do not want to need heat to loosen the bond.

1) Is Blue strong enough to not come loose under heavy recoil?

Or,,,

2) Should I use a different color of Loc-tite?

Blue wil work fine. It has a strong enough hold that vibrations won't losen it, but the parts can be removed with regular tools. Blue is what most gun companies suggest using.
 
Recommend using the product called "Guntite" its a locktite product (IIRC), and holds well, yet comes apart with tools fine also.

Loctite has a range of products, coded both by colors (blue, red, green, etc) and numbers as well (242, 271, 272, etc.). Using the wrong one will mean a hassle.

Guntite is for gun screws. I don't know which one it is in the industrial lineup, but I know it works well for me. You can get it nearly everyplace that carries sporting goods.
 
Blue will work. I've used it on a Glock 21 (45ACP) and it worked just fine. I do normally use red though, I was just out at the time...
 
Blue doesn't require heat to remove, but is intended for medium to large fasteners. For small fasteners (the size of sight screws) the correct Loctite to use is purple.

I keep both purple and blue on my bench. I don't let red in the door. That's for things like suspension bolts in my off-road Jeep.
 
I just want to lock down the sight adjustment screws,,,

It hasn't happened to me yet,,,
But I keep reading about people losing their sights at the range.

I just want something to ensure that event doesn't happen to me.

I bought a small tube of blue on my lunch break,,,
I'll try it on one of my stainless guns.

Blue Loctite should be sufficient for most threaded fasteners on firearms. I use red for jobs like staked front sights and plunger tubes. It is removable but does require some heat (around 350 to 400 degrees will melt it). No torches, a soldering iron tip on the fastener will do it. When using Loctite it is very important to thoroughly clean everything off of the threads. Any oil or grease will cause it to fail. Acetone or lacquer thinner works.
 
The meprolight night sight instruction sheet recommends using Loctite 609 on them when being installed. I have never seen this number of Loctite offered anywhere in my area. Anyone familiar with this variation?
 
Loctite 609 is a retaining compound designed for non threaded parts such as bearings or pulleys on a shaft. It works very well for dovetail sights, I have used it for years. It is color coded green.

Been dere dun dat twice, once during a match, the second time preparing for a match. Now it's Loctite blue #242 on my sights and scopes and I don't have that problem anymore.
 
I guess I've never had a part of a gun that blue wouldn't hold... and I wouldn't want the hassle of applying heat (especially 245F) to remove a part that would have held just as fast with blue.

To each his own.
 
You use red on GUNS

Do you use an impact to get them apart?

Scope bases on my 06 loosened so I used 242 Blue. They loosened again. I cleaned the threads reeeaaallllyyy well and used red. So far they haven’t budged. IF I ever want to remove the mounts I’ll stick a soldering iron on the screw heads for a few seconds and the screws “should” come right out. It’s not hard to get a small screw to tem in just a few seconds. The custom fire control for my AR came with Red LocTite and instructions to use it on the adjusting screws. You don’t want your trigger system going haywire while you’re shooting.

I pretty much use 242 Blue on everything I don’t want to come apart. And I ALWAYS try Blue before going READ.

Have a nice day Comrades. :eek:


That’s a joke for those that missed it. :)
