Mystery ringing inside Stock head

[Jerry Andrews]

I'm sorry, I didn't mean to be comical. I think it happened from birth with my ear size. My ears at birth were the same size they are now. Mom almost had to have a C-section over it.
Back to your Parker. I am a qualified gunsmith, have been working on guns since 1974. I'm guessing your problem does not have anything to do with the brass pin, but probably does have something to do with top lever. The brass pin, if I'm picturing this correctly, is simply imbedded in the wood. I can't imagine how that would make any ringing noise. And if one hammer was hitting the pin, unless the pin is put in cocked, they should both hit. Try holding on to the top lever while you dry fire the gun. In fact, hold various parts of the frame while dry firing the gun. It could also be the sear once disengaged. It really could be a few different things.
And I'm not an advocate of stove bolts, except on stoves, or brass pins, except on brass beds. Jake

Brent, I was not trying to be sarcastic at all. I was just trying to be helpful. You made the statement that you thought it might be a broken hammer spring(Main Spring) and I commented that I never seen that happen on a hammerless gun. I have seen broken main springs on hammerguns though. I have a few Parkers that ring when dry fired and I attribute that to vibration that is sent through the action caused by the hammers falling on an empty gun. Parker mainsprings are very strong and this type vibration is indicative of that.

If I offended you I apologize....

Brent, I had a GH 12ga Damascus that rang like a church bell when shot. It was an old gun and well used, but probably had not been shot for a long time. The ring was in the top lever, like Bill Murphy's gun, but it went away after it loosened up with use.

Brent, I will differ with your opinion about gunsmiths. I feel you will get more information here than you will get with a gunsmith. Many gunsmiths have very little experience in the field with the guns they work on. My suggestion is to tape any part you suspect is ringing, top lever first. Sorry you feel you got no help here.

Brent,

Have you thought about taking the stock off of the receiver, reassembling the receiver, and testing to see if you still hear/feel the vibration? You'll have much of the inards exposed for evaluation.
