I have an adjustable gas key I would like to install and stake in place.

Do I need to 'push' the material out of the way when removing the old key so I can re-stake the new key with the same material or is cutting a minimal amount to free the screw ok?

Also any tips on re-Stakin the new key would be appreciated.

If you can knock the displaced metal back it'll make getting the screws out a lot easier.



As far as staking teh new one one, it's pretty straight forward with either a chicle or a punch.  Just have to displace the metal to "lock" the screws in place

You may want spare screws in case you strip the hex head.

You should ALWAYS replace the carrier key screws with new ones.

The new adjustable gas key came with a new set of screws.

To clarify, stake the key into the screws, not the screws into the key.

It is good that you are looking to do this right the first time. I have had more guns brought into my shop from the owner removing, then reinstalling the gas key without re-staking than any other problem.

I have also seen people glue their bolt into the carrier with locktight when they put back on the key so that is another thing not to do.


Use a proper torque wrench to install the screws on your gas key, proper torque is very important. I dont have the numbers at my desk but they should not be hard to find on this awesome sight.

The current torque spec is 50-58 inch pounds. The old torque spec was 35-40 inch pounds.

You are supposed to use a sealer under the key around the gas port as well.

It has been advised to not use a punch to stake the key unless you are doing the field staking method. I would recommend using the MOACKS Plain.

What type of sealant should I use, and if it's hard to find where should I get it from?

Thank you, everyone for all the helpful tips. I haven't done any work to it yet. I'll try to update this thread with any progress/problems and maybe even a pic or 2.

LMT uses Loctite 518 sealant.

Young Manufacturing uses Permatex high strength thread locker gel (Part Number 27010).

And Colt calls for Permatex Aviation #3, I wouldn't go by any recommendation by Young, they don't believe in staking carrier keys.
