An explanation from Young about staking their gas keys

[5pins]

If using Permatex and torqueing works for Young then great. The point is to make sure that the key stays tight.
However I have to wonder about a couple of his statements.

“ The Mil Spec. also calls for the gas key bottom surface to be “SEALED” with Permatex gasket sealer.”

I took off a lot of carrier keys when I was in the Army and never saw any thread locker or gasket sealer compounds on any of them. Also the TM doesn’t call for any to be used when replacing.

“ Don’t use a hammer and a punch! You can stretch the thread on the screw and now you have a loose screw that will eventually break if the gun even fires.”

The TM does in fact call for the repairer to do exactly what Mr. Young is saying not to do. I can’t imagine that the military has been doing it wrong for all these years.
