I believe that the gas key gets too hot for lock-tite to work properly. You would be better off getting the key and bolts staked properly.

appreciate the response, but are you talking about the BCG or the Gasblock. Can the set screws be staked on the gas block

Don't use any Loctite. It just doesn't have the temperature resistance you're going to need for an application like a gas-block.
Use Rocksett, the same stuff Surefire recommends for securing the barrel threads of their suppressor adaptors. It has the breaking strength of blue Loctite, but much,much higher temperature resistance. |

A handy tip for removing red Loctite . . . put a soldering iron on the head of the screw for 5-10 minutes . . . the Loctite just melts away. That doesn't work with Rocksett. I try not to subscribe to the "it's good enough" conclusion when I know there is something better out there. |

Love these LockTite responses as they will get people into trouble. There are five different LockTite products available for general use in addition to numberous ones available to industry only. If you go by color your in trouble. You need to specify the number of the product –– 222, 242, 271, 290 or 640. 640 hss the highest strength and over the years has been two colors too my knowledge - red or green. There are three colors LockTite uses - red, green or blue. Get the wrong product number because you used color and you in deep do do. Then again I can use another cheap rifle because someone used the wrong product. Dealer was happy to part with the trade in at a deep discount.

So which number is the correct one then, if not by color?

There are three versions used by us common folks;
222MS - purple 242 - blue 262 - red The remaining versions are specialized for their application. Read the label before using. Also note that strength and temperature resistance are not synonymous, which is why I still prefer the Rocksett. Rocksett is clear by the way, so there's no mistaking it. |

I've yet to see a properly loctited gas block fail. I'm sure it has happened, but I've not experienced it.
To answer the other question, you can stake any screw that has metal around it to deform. So while you MIGHT be able to stake these depending on your gas block and how it's configured, I wouldn't do it that way. |

I used red loctite AND safety wired the screw heads together. Even if the block gets hot enough to weaken the loctite, they aren't going anywhere unless I break the wire.
The downside is you have to drill the screw heads, and acquire .020" stainless safety wire (I would also recomend pliers but those were only like $4 at harbor freight)... safety wire isn't really cheap, considering you only need a few inches of it! How to safety wire Edit: I can't spell |

I have used Loctite (Green)290 for bedding & securing gasblocks/screws without any issues.

Loctite Red 271.
It's way the hell stronger than Rocksett, heat or no heat. I've used both extensively. |
